Kirill Eremenko: This is episode number 177 with aspiring Data
Scientist, Zach Loertscher. Welcome to the Super Data
Science Podcast, my name is Kirill Eremenko, Data
Science Coach and Lifestyle Entrepreneur and each
week we bring inspiring people and ideas to help you
build your successful career in data science. Thanks
for being here today and now, let's make the complex
simple.
Welcome back to the Super Data Science Podcast,
ladies and gentlemen. Super excited to have you on
board and today we had quite an interesting episode
with an interesting guest, Zach Loertscher. Zach is an
aspiring Data Scientist who has made huge progress
in terms of building his own career and building his
online presence in the space of data science. And
interestingly enough, the way I actually found out
about Zach was through a blog post that he made with
a list of Data Scientist mentors to connect with to
follow. And I was so inspired by that idea, I thought it
was a great idea and a great way to help others, that I
had to invite Zach onto the show and find out about
how he actually thinks of data science, of the
community, and of building your presence here and
also playing your part, your role in helping others.
That's what we talked about quite a lot on this podcast
and you'll get some very valuable insights in how you
can better help the data science community and build
your own online portfolio. Also, we talked about his
thoughts on data science education, and in this
podcast we actually flipped it around and Zach asked
me a couple of questions, which I was totally not

expecting. And I got to answer a few questions on the
show as well, so you'll get to know a few of my
thoughts, especially on the situation with data science
education, with universities, with online courses and
things like that. All in all, quite a fun episode, a bit of
a different style this time. I hope you enjoy it. I can't
wait for you to get straight into it. Without further
adieu, I bring you Zach Loertscher, an aspiring Data
Scientist.
Welcome back to the Super Data Science Podcast,
ladies and gentlemen. Today I've a very exciting guest
on the show, Zach Loertscher. Zach, welcome to the
show. How are you doing today?
Zach Loertscher: Doing really well, I'm excited to be here.
Kirill Eremenko: Excited to have you here. Tell us, where is your
surname from?
Zach Loertscher: It is from Germany. Swiss, Germany.
Kirill Eremenko: Swiss, Germany. I was in Switzerland in the Swiss-
German part for a whole month in march this year.
Very nice place actually, it's very neat and very clean.
Have you been back since?
Zach Loertscher: I haven't, I've never been there. You know more about
it than I do.
Kirill Eremenko: Oh, I think you will love it when you go.
Zach Loertscher: Yeah.
Kirill Eremenko: Well Zach, first of all I wanted to say a huge thank
you. The reason why I reached out to invite you to this
show is because I saw a list that you put together and

somebody else represented in image format, which is a
list of top mentors in data science. I was very humbled
to see myself on the list, that was very exciting for me
but that's not the reason of course, why ... it's not, "Oh
just because of me." The thing is, I found it very
inspiring that you went through the trouble of actually
putting together a list of mentors in data science,
people who you can learn from and who inspire you to
grow in this space. So, thank you so much for putting
that together and for sharing it with all the aspiring
Data Scientists. Today, I just wanted to talk more
about that and your journey in data science, how does
that sound to you?
Zach Loertscher: That sounds awesome.
Kirill Eremenko: All right. Well, tell us a bit about yourself. Where do
you live? And what are you currently doing in your
life?
Zach Loertscher: Currently I live in Idaho, in Rexburg. Not many people
know about this place but it exists. I'm going to BYU
Idaho, pursuing a degree in business analytics and I
am about to graduate in a few weeks. Yeah, I'm really
excited about data science. I've been studying it since I
did my internship down in Utah, and I was working for
their business intelligence team and I found this really
cool tool called Tableau. That was just really, really
cool to me. Then I was also having to learn how to
program with Python 'cause we were doing a lot of data
transformation and I was going through one of those
long days of going through tutorials and trying to
finally find what you actually are looking for. I

stumbled on Kaggle and I was like, "Oh this is cool.
What are these people doing?"
Kirill Eremenko: Yeah.
Zach Loertscher: That's how I discovered machine learning and data
science and since then it's just been a really fun ride.
That's a little bit about me and my stage in life. Yeah.
Kirill Eremenko: Fantastic. So you were doing a bachelor's in business
analytics?
Zach Loertscher: Yeah.
Kirill Eremenko: Okay. Was it a four year bachelor?
Zach Loertscher: Uh huh.
Kirill Eremenko: And what was the university?
Zach Loertscher: BYU Idaho.
Kirill Eremenko: Oh okay, okay. I didn't catch that. Okay, cool. I was
surprised to learn that, it was a very apt degree for
getting to the profession of data science. You don't
hear many degrees in business analytics, is that a
recent degree that they've come up with or has that
been around for a while?
Zach Loertscher: Yeah. Well, it's been here for a few years. They actually
just created a data science degree but I'm already so
far into it, I'm like, "Well, I'll just finish with business
analytics and pick up all the other stuff along the
way."
Kirill Eremenko: Might as well, might as well.
Zach Loertscher: Yeah.
![Page 6: SDS PODCAST EPISODE 177 WITH ZACH LOERTSCHER › uploads › … · does a lot of data warehousing and he started in reporting and I was like, "You know, this looks interesting to](https://reader034.fdocuments.net/reader034/viewer/2022042401/5f101a437e708231d4477534/html5/thumbnails/6.jpg)
Show Notes: http://www.superdatascience.com/177 6
Kirill Eremenko: Okay, cool. Why did you get into business analytics in
the first place? Because that was what, four years ago?
Is it because of what you heard about data science and
what's going on in the world? Or was there another
reason?
Zach Loertscher: Actually my dad, he works in business intelligence. He
does a lot of data warehousing and he started in
reporting and I was like, "You know, this looks
interesting to me. I know there's high demand for it."
And I didn't actually really know about data science
when I started out on this degree. I was like, "I'll just
go along this path that my dad has gone along." It
wasn't really until my internship when I really
discovered data science and what it is and I found out,
"Hey, business analytics actually fits into this a little
bit."
Kirill Eremenko: Yep.
Zach Loertscher: And it just was a really happy accident, to be honest.
Kirill Eremenko: Yeah, yeah. That's pretty cool. Okay. So you're on this
journey, but tell me this, many people who are
studying are just happy studying. Yet, you go above
and beyond to actually find online courses, like you
mentioned before the podcast, I think you did one of
our courses or at least a couple courses already, then
you finding resources and you put a list of mentors
together who inspire you in data science. What pushes
you to do that? Why did you decide to go that extra
mile?
Zach Loertscher: I think it's mostly been knowing that LinkedIn is such
a powerful networking tool and I've been really trying
![Page 7: SDS PODCAST EPISODE 177 WITH ZACH LOERTSCHER › uploads › … · does a lot of data warehousing and he started in reporting and I was like, "You know, this looks interesting to](https://reader034.fdocuments.net/reader034/viewer/2022042401/5f101a437e708231d4477534/html5/thumbnails/7.jpg)
Show Notes: http://www.superdatascience.com/177 7
to push for a stronger network as I'm approaching
graduation. That was really the first place I went to
because for a very long time, for I don't know, four or
five months, I would just look at LinkedIn and look at
what other Data Scientists were saying and just follow
them and say, "Oh, that's cool, that's what they're
doing." But I wasn't really posting anything. I noticed
that a lot of people on LinkedIn talked about, "It's such
a great networking tool, it brings people together, it
helps you find a job." I was like, "I'm gonna try this out
and I'm ready to contribute. I've been looking at this
for a while, I've been studying it for a while and I want
to contribute, I want to make a difference."
That's really what prompted me to put it together. I
remember when I was just starting at data science,
someone else had posted a list of a bunch of Data
Scientists I should follow and that's when I really
started learning about it. So I was like, "Let's pay it
forward a little bit." And I had no idea that, that post
would be so popular, but it was really exciting, it was
really cool and that's really my motivation. One of the
best parts about it is getting messages from people
just thanking me. I've heard other people say the same
thing 'cause I haven't done too much, but just
thanking me for contributing what I have, saying,
"Hey, you helped me with this." And that's just one of
the most satisfying parts about it all. Yeah.
Kirill Eremenko: Yeah, yeah. Gosh, and you actually helped me as well,
apart from finding YouTube and watch this podcast.
The way I found your list, I think Ben Taylor, you
know Ben Taylor?

Zach Loertscher: Yeah.
Kirill Eremenko: He recommended me to look at your list for guests to
invite to Data Science GO 2018 and-
Zach Loertscher: Oh cool.
Kirill Eremenko: Yeah, and I was going through your list, I was like,
"Oh, I haven't met this person, I haven't met this
person." And I just went through every single one and
invited everyone to connect on LinkedIn. It was a great
opportunity for me to connect with the top influences
in the field of data science, so thank you. It really
helped me out as well.
Zach Loertscher: Yeah, you're welcome.
Kirill Eremenko: In fact, we're probably gonna share this on the show
notes for this episode, for all listeners, I highly
recommend going to check it out and then just
connecting with every one of those influencers there
and following them, and learning from them just as
Zach did, and I'm learning and others are learning as
well. Yeah, that can be a good addition to peoples
LinkedIn networks. Tell us a bit about, if you don't
mind, since you made the decision that you want to
build this network and you want to contribute back to
the community, how have you felt the impact? You
mentioned that people have said thank you, but has
anything else happened for you in this period of time?
Zach Loertscher: I feel like by posting, you develop these ... they're not
real life relationships but there are certain people who
will always comment and you develop these
friendships almost on LinkedIn, which is awesome.
But also, if you think about LinkedIn and the platform
![Page 9: SDS PODCAST EPISODE 177 WITH ZACH LOERTSCHER › uploads › … · does a lot of data warehousing and he started in reporting and I was like, "You know, this looks interesting to](https://reader034.fdocuments.net/reader034/viewer/2022042401/5f101a437e708231d4477534/html5/thumbnails/9.jpg)

and what it's designed to do, it's designed to keep you
on the site as long as possible. They get their revenue
through ads or through hooking you up with a
company or someone else. So if you have a lot of posts
and you're putting a lot of content out there that
people are enjoying and engaging with, when a
recruiter searches for you, it will boost you in their
search results. 'Cause they want recruiters to find
people who are active on the site so that the recruiters
will stay on the site longer. At least, that's my theory.
That's basically what happened for me, is as I was
posting more and engaging more with the community,
I was getting contacted by a lot more recruiters. It
really wasn't until I started posting so much that, that
happened. So that was just an unseen benefit for me
and one of the best ones for me because it's led to a lot
of opportunities and a lot of connections.
Kirill Eremenko: Yep, yep. That's definitely what LinkedIn is all about,
and putting yourself out there and building your
brand and portfolio and helping others is gonna get a
lot of attention going your way. Yeah, that's a good
start, you're definitely on the right track with your
career. You haven't even graduated yet and you
already built up this portfolio, how does that make you
feel?
Zach Loertscher: Just really excited to continue to engage with the
community.
Kirill Eremenko: Yeah.
Zach Loertscher: I just feel really privileged and blessed to have that
opportunity, that there is a good group of people that

Show Notes: http://www.superdatascience.com/177 10
see my posts, that's exciting for me 'cause I get to
share my journey with other people and hopefully
inspire other people who come from a similar
background or maybe are just beginning. And maybe
share some encouragement or motivation, share some
of my discouragement to help them feel encouraged
'cause it's a hard journey for everyone. That's the
exciting part for me.
Kirill Eremenko: Gotcha. How much time on average do you think you
spend per day on LinkedIn?
Zach Loertscher: Too much time. Probably an hour, maybe an hour and
a half.
Kirill Eremenko: An hour and a half.
Zach Loertscher: It depends on the day, just how busy I am, but yeah
probably around there.
Kirill Eremenko: Does it feel like work to you? Or does it feel more like
you having fun?
Zach Loertscher: When I'm posting, it feels more like ... I don't know, I
put a lot of thought into it and it takes a lot more
thought than when you're just scrolling, right?
Kirill Eremenko: Right, right. Yeah, yeah.
Zach Loertscher: But no, it's really exciting 'cause I've been following a
lot of these people for a long time and you get to see
their journey as well. You also discover a lot of new
trends in the field, new things that people are
discovering, new cool projects that someone else did.
I'm always seeing these cool new innovations that
people created with technology or deep learning, things
like that. That's really exciting for me too.

Kirill Eremenko: Who would you say is your favorite Data Scientist to
follow on LinkedIn?
Zach Loertscher: My favorite to follow, I'll think about this for a second.
Kirill Eremenko: I see you have commented on quite a few posts by
Randy Law recently.
Zach Loertscher: Yes, yes, yeah.
Kirill Eremenko: Would you say Randy might be that candidate?
Zach Loertscher: Yeah, he's probably one of my favorites. He's always
posting something really positive and motivational,
and also posts these awesome lists of resources. And if
someone else is asking me for help, I usually just send
them one of those lists of resources 'cause they're so
awesome. Yeah.
Kirill Eremenko: Yeah. Yeah, okay. That's very cool. All right. That's a
great way of getting this knowledge, by following the
people that are at the top of data science or the cutting
edge of data science and they're trying to break it
down in simple and complex terms and then you can
just learn from them and see what resources they use.
You get ahead of the game, you skip all that searching
that they are doing and they save you a bit of time that
way, I guess. That's very cool. What about your future
career? You're graduating in a couple weeks. That's
very exciting and congrats on that.
Zach Loertscher: Thank you.
Kirill Eremenko: Where do you think you're gonna go from there? Have
you already lined up a job? Or is there an industry
that you're interested in?

Zach Loertscher: Yeah, actually I have. I don't know if I'm supposed to
keep it on the down low or not, I'm not sure.
Kirill Eremenko: Probably stay on the safe side but maybe just ... all
right, congratulations. If you've lined up a job that's
fantastic. But yeah, tell us once you have a job, are
you going to continue learning? What kind of data
science are you going to continue learning? In what
area are you doing to direct your education?
Zach Loertscher: Yeah, I'm really fascinated by the healthcare industry,
actually, and a lot of the innovations that are
happening there because one of the projects that I did,
there's a really cool data set on Kaggle about breast
cancer. Actually, it was the first data set that I ran a
logistic regression on and it was really fascinating to
be able to see I can get 95% accuracy at predicting
breast cancer. Something that nobody likes and
something that everyone's researching to try to get rid
of, you can use and harness the power of machine
learning to help with this issue. So that's the field that
I'm hoping to end up in, really. Is in that field of using
machine learning within healthcare, because the
traditional healthcare system has just been, you go in,
you see a doctor, someone who's been to school for
several years and they're very wise, they're very
practiced. But there's no way that you could ever
harness all the data that the medical professionals use
in one day without using Data Scientists. And that
just makes me so excited.
I saw a video the other day of ... I don't remember
where it was but they were using deep learning to spot
cancer cells in realtime, draw a little circle around it
![Page 13: SDS PODCAST EPISODE 177 WITH ZACH LOERTSCHER › uploads › … · does a lot of data warehousing and he started in reporting and I was like, "You know, this looks interesting to](https://reader034.fdocuments.net/reader034/viewer/2022042401/5f101a437e708231d4477534/html5/thumbnails/13.jpg)

through a microscope in realtime, and it was all based
off of these deep learning algorithms that they had run
on these images. It's just fascinating to me, so that's
where I really want to end up is at the healthcare
industry, 'cause I think there's so much potential there
and a lot of potential to do good as well.
Kirill Eremenko: That's a very noble cause. Have you heard of the
conference called HIMSS?
Zach Loertscher: Uh uh.
Kirill Eremenko: It's spelled H-I-M-S-S, and I just recently found out
about it myself, just a few days ago. I think this one is
held in February and it's massive, it's like 40,000
people attend and it's all about healthcare and
technology, the intersection and ... it's not all just data
science but there's a ... I haven't been to it but I heard
about it from a data science podcast, I'm assuming a
large portion of it is dedicated to data science. Why I'm
mentioning this is because first of all, it stands to
show that this is a very rapidly growing industry, or
intersection of industry of healthcare and data. Also,
maybe you and others who are interested in healthcare
can check it out. It's HIMSSconference.org, might be a
good thing to attend maybe.
Zach Loertscher: Yeah, absolutely. I'll definitely look into this.
Kirill Eremenko: Okay. I understand it's a noble cause to help people
with healthcare and apply to data science in that area,
is there any ... there's also other areas of where you
can apply data science. Finance, you can apply data
science in safety, in full detection and other areas.
How did you single out this one? We already
![Page 14: SDS PODCAST EPISODE 177 WITH ZACH LOERTSCHER › uploads › … · does a lot of data warehousing and he started in reporting and I was like, "You know, this looks interesting to](https://reader034.fdocuments.net/reader034/viewer/2022042401/5f101a437e708231d4477534/html5/thumbnails/14.jpg)
Show Notes: http://www.superdatascience.com/177 14
understand why, that you want to help people, but
what thinking process did you go through? Did you
just meet someone who is in healthcare and you got
inspired? Or did you go through lots of industries and
you picked this one? Or was it just because you were
able to get a job in this space and then you learn more
about the company and you were inspired by what
they do? Can you walk us through the thinking
process of somebody's who's studying, how do they
pick an industry that they're gonna go into?
Zach Loertscher: Yeah, absolutely. I think one of the most powerful
things that someone can do before they decide on an
industry, like, "I'm gonna go in finance or I'm gonna go
into healthcare.", or whatever it might be, is reach out
to people who are currently working in that industry.
Better yet, people who have recently been hired in that
industry. For me, as I was pondering about going into
the healthcare industry, I did reach out to a few people
who do work with data from the industry, and they
both spoke very highly of it. They said it's fascinating
the things that you learn. So for me, that was a really
good motivator. Also, just thinking about where ...
data science has come a long way for business but I
think there's a lot of potential for growth still in the
healthcare industry. I think business has been on the
bleeding edge, obviously there's research, but business
has been on the bleeding edge of using data science.
And I think healthcare is coming to that point where
it's going to be using it a lot more.
So, just spotting that opportunity gets me really
excited, like, "There's gonna be a lot of jobs in this
![Page 15: SDS PODCAST EPISODE 177 WITH ZACH LOERTSCHER › uploads › … · does a lot of data warehousing and he started in reporting and I was like, "You know, this looks interesting to](https://reader034.fdocuments.net/reader034/viewer/2022042401/5f101a437e708231d4477534/html5/thumbnails/15.jpg)
Show Notes: http://www.superdatascience.com/177 15
field, there's gonna be a lot of opportunities." So I
think just being aware of what's happening in the field
and thinking, "Which industry could really explode
next?" But probably even more importantly is talking
to people who are in that industry so that you get a
good idea of where it's at and is it going to explode
next?
Kirill Eremenko: Yeah. No, that makes it very clear. So you are
identifying an opportunity for the situation to grow,
and you're right, in business, competitive pressure
makes companies adopt newer and newer technologies
all the time. And that might not really be the case in
healthcare, it might take a bit longer for that to
happen. Okay. That's very good. The other thing I
wanted to ask you is actually what you asked me
before the podcast, you mentioned that you are
interested to find out about degrees. Is a formal
education required in data science? Or are online
degrees an exception? Can you repeat that question?
What is it exactly on your mind when you're pondering
that?
Zach Loertscher: Absolutely. As a new graduate, and I've found that
position ... I'm thinking a lot about grad school and
traditionally, in the field it has been, "You need a
graduate degree." But the cost of education everywhere
is skyrocketing, but also the availability of open source
or very low cost education online is also skyrocketing.
So I'm wondering what your take is on these online
certificates, maybe if people go to Corsair, or Udacity,
or Udemy and learn about these things, do you think
that companies will begin to value those certificates as
![Page 16: SDS PODCAST EPISODE 177 WITH ZACH LOERTSCHER › uploads › … · does a lot of data warehousing and he started in reporting and I was like, "You know, this looks interesting to](https://reader034.fdocuments.net/reader034/viewer/2022042401/5f101a437e708231d4477534/html5/thumbnails/16.jpg)
Show Notes: http://www.superdatascience.com/177 16
much as they value an advanced degree? Or do you
feel like it'll keep on the same trend that it's been
following?
Kirill Eremenko: Okay, that's a good question. What I would say is that,
I think those certificates ... and this might be a bit of a
controversial answer but I think those certificates,
those online certificates are gonna be valued less, and
I think university certificates are gonna be equally
valued less. The reason I say that is because ...
especially once you already have a degree, which I
personally think if somebody's looking to starting a
degree, at the very beginning, you can go without it.
But especially if you already have a degree and you
already have a job, from here what counts is your
experience, is your ability to demonstrate that you
have industry or industry level experience in the field.
And that's all that matters because people don't really
care about, or employers don't really care about
another paper.
At the end of the day, whether you have a paper or
not, what they care about is, can you solve their
problem, can you add value to their business, can you
add value to their bottom line of their profit and loss
statement. And having a degree might indicate the
possibility of you being able to do that, but there's so
many other ways right now online that you can
demonstrate that much more efficiently and much
more succinctly. Whether it's by going, like you said,
to Kaggle and doing projects there and adding them to
your portfolio, or using, again, Tableau and building
an online Tableau public portfolio and showcasing

things there. Whether you're on a website or blog and
sharing information there, you don't even need to blog
these days. As you've noticed, you just share stuff on
LinkedIn and ...
Well, you can't really share if you have a job and
you're working there and you have made some
breakthroughs, you can't really share those things
because that's sensitive information. But you can
share the techniques that you use, again, if they're
publicly available techniques, or ideas that you came
up with if you're not violating any intellectual property.
Or just to share thoughts on other data sets and how
you would approach other challenges. Ultimately, if
somebody's signing up for a degree such as a master;s
degree, there has to be an intention in mind. You
cannot just sign up for a degree and say, "Okay, I'm
signing up for this degree just for the sake of doing it,
just for the sake of having a paper." That's definitely,
in my view, a waste of time.
Zach Loertscher: Yeah.
Kirill Eremenko: If you have an intention in mind, for instance, I want
to have, not just a data science job but like in
healthcare, which is really, really great stuff, but I
want to have a Senior Data Scientist, Senior Machine
Learning Expert in the field of healthcare. Or maybe,
let's say Senior Machine Learning Expert in cancer
prevention. You have a very specific goal in mind and
that's hwy you would pursue a master's degree in
machine learning or something like that. Well, as long
as you have this intention in mind, all you have to do
now is replace the word degree, which I find is like a

safe bet, or a person that ... like if somebody who
would take a degree is ... maybe not always the case,
but in my mind, it might be somebody who just lacks
the proactive approach to be creative and come up
with an alternative solution that might be faster, but it
might be a bit more difficult.
Let's say this one, you go and you create a portfolio of
projects and you share them through LinkedIn
consistently for six months, that are specifically either
about machine learning or cancer prevention using
data science, or and machine learning. And if you keep
doing that for six months and you share your work on
one project every four weeks, let's say in six months
you share six massive projects that you did, you
described them, you spend a week or two just writing
that blog post out, in addition to the two weeks that
you spent on the project. So in six months, you have
six big projects that you shared with the world that
added value to businesses, and people, and
professionals, and aspiring Data Scientists, and that is
going to give you so much more visibility than just the
paper that you can share on your LinkedIn or in your
resume. The process is gonna be faster.
A master's degree is gonna take you at least two years,
or at least one and a half years. This can be done in
six months and it also is gonna be more current
because those degrees that you see in universities,
unfortunately, they are usually outdated by the time
they are released. Because to go through the formal
approval process in the university, they have to put
the curriculum together, get it approved by the Dean,

by the faculty, by the university, et cetera, et cetera, et
cetera. By the time it rolls out, it's already been at
least 6 to 8 to 12 months and the world's moved on
from those case studies, from those methodologies.
Not that far but there might've been a breakthrough or
some other discovery that is not included in the degree
and therefore you're like, what you're studying or what
you're paying money for, there's already something
newer out there. Whereas if you're doing it yourself,
you can always adapt. All those projects take a month
at the most. That's my take on it, especially having
completed a degree and having a job, you're not
pressed for time, you have a way to sustain yourself
and you have this hopefully free time to work on
projects, I would just go do it my own way.
Zach Loertscher: Yeah, yeah. Absolutely, cool. Wow, that's a very
powerful answer, I really appreciate that. I got some
gold nuggets of wisdom in there.
Kirill Eremenko: No worries, man. Sometimes it's sad to see people
losing time, time is the most precious thing we have. I
get the appeal of a degree, whether it's a bachelor or a
master's degree because it's what our parents did,
what our grandparents did, what everybody's
expecting you to do. It's a big scary to go without a
degree, or without a master's degree, or without a PhD
because still, it has some way, this feeling that it's an
accomplishment, it's like a check, "I checked this box
off." But ultimately, if you'll even look at the most
successful people in the world, most of them are drop
outs, there's Mark Zuckerberg, Steve Jobs, they never
completed universities, as far as I know. I might be

mistaken somewhere here, but most of these people,
they realize that, "Hey, no, there's something else I can
do." It's about making your own rules and playing by
your own rules.
University and all those degrees, they are rules that
have been created over time and society has imposed
upon itself and accepted. And by following them, you
follow a safe path that is guaranteed to get you
somewhere. And even though, it's just the perception
of those guarantees. Those guarantees are actually
fading, dwindling away exponentially as we move
through the years, as we move into the world of
internet and technology and more people are actually
coming online. This guarantee is actually dwindling
away, it stays in our mind through this upbringing,
through our cultural education and things like that,
but in reality, this is the best time probably in the
history of human kind to break rules and play by your
own rules. I'm not talking about legal rules, I'm talking
about cultural rules of the way that we are used to
building our careers and education and so on. The
people that break the rules are the people that create
their own rules and play by their own rules, those are
the people that get ahead the fastest and succeed the
most.
Let's say for instance in your case, you've created your
own rules by saying, "Hey look, I want to give value
back to the community on LinkedIn." That's already
not what most people do, 99% of people don't ... I don't
know how many people have or don't have LinkedIn
but let's say out of the people that do have LinkedIn,

99% of people don't share valuable blog posts of their
own creation. But then you take it even further, you're
like, "Well hey, how about not sharing just a blog post,
how about sharing a list of mentors, people who have
influenced me. Let me collate that information." That's
like you creating your own rules, nobody else had
thought of that, especially since they said, "Oh maybe
a few people have." But you were like, "Let me do that
from my perspective."
Look what that's gotten you, so many people have
contacted you, so many people have gotten value out
of it. And right away, as soon as you do something
that doesn't conform with the rules, you ... there's a
saying, "If everybody" ... I don't remember exactly how
it goes, but, "If everybody around you thinks you have
a stupid idea, it's either they're true, they're right, you
have a stupid idea, or you're on the verge of a
breakthrough." Right?
Zach Loertscher: Yeah.
Kirill Eremenko: I'm not saying it was a stupid idea, but I'm saying if
you're not conforming with everybody else, you might
not do anything, you might be wrong, but on the other
hand you might be right and therefore you will have
this exponential leap all of a sudden. And "Bam!", in
one blog post you have thousands of followers, people
are contacting you and you added tremendous amount
of value to others. So yeah, I guess the same goes for
education and stuff like that.
Zach Loertscher: Yeah, that's awesome.

Kirill Eremenko: Yeah. That's my take on these things. Any other
questions? I like this approach. Do you have any other
questions for me that I might be able to help you out
with?
Zach Loertscher: I'm curious a little bit about your own journey. You're
a successful entrepreneur, you've started your own
business, you're telling me you've got people from all
around the world in your company and I also share
this same philosophy. I know I'm finishing a degree
but as I come along in understanding the power of
teaching yourself and seeking resources on your own,
I've changed my mindset a little bit there as well. One
of the parts that I've struggled with and I know a lot of
other people struggle with is the discipline that is
required. You go to school and it's very structured and
you have accountability in place with professors, or I
don't know, maybe you're facing pressure from
someone else, and it is a very new idea to take your
own path and take charge of your own education. So,
I'm wondering, on your own path, what has helped you
the most to, I don't know, keep that drive, keep that
motivation, and keep that structure in place? 'Cause
that structure is very important.
I've definitely experienced just traveling down the
rabbit hole on 15 different web pages, all in one day
and not really learning anything at all. I'm curious,
what tips or techniques have you found to be the most
helpful in disciplining yourself and creating an
organized learning environment for yourself?
Kirill Eremenko: Oh, that's a good question. Oh okay. All right. Well, I
guess one thing is I don't like wasting time, that's
![Page 23: SDS PODCAST EPISODE 177 WITH ZACH LOERTSCHER › uploads › … · does a lot of data warehousing and he started in reporting and I was like, "You know, this looks interesting to](https://reader034.fdocuments.net/reader034/viewer/2022042401/5f101a437e708231d4477534/html5/thumbnails/23.jpg)

number one, because I don't like setting myself back
or putting myself at a disadvantage because I'm being
lazy and knowing that, that will cost me time later on
because I know I probably won't get that time back.
Realizing that, that you only get every hour, or day, or
even I think in more terms of years. Like if this is when
I was doing my degree or when I was working at
Deloitte, I knew that if I fail at something, failure's
okay, but you learn. But if I fail because I'm lazy
during [inaudible 00:36:13] then that's gonna set me
back in terms of my being able to progress through my
degree, or through my promotions, and so on. So I was
like, "I can't afford to do that because I'm responsible
to the future version of myself. Future Kirill, he's
gonna be upset with me or I'm gonna put him at a
disadvantage, that's not cool." That realization is
important, I guess.
Zach Loertscher: Yeah.
Kirill Eremenko: The other thing is, have a vision. What do you want? If
you don't have ... they have a saying that, "Without a
target, you're gonna miss every single time." Right?
Have a target, have a goal. Where are you going?
What's the purpose of what you're doing? In terms of
organization of your work, there's a great methodology
by Tony Robbins called the RPM, called the Rapid
Planning Method. He talks about identifying the result
that you want, then setting a purpose behind that
result, which is the emotional driver behind what you
want. Let's say you want to learn R, in your degree you
might know Python but you want to learn R by the end
of the year. So that's your result, "I want to be able to
![Page 24: SDS PODCAST EPISODE 177 WITH ZACH LOERTSCHER › uploads › … · does a lot of data warehousing and he started in reporting and I was like, "You know, this looks interesting to](https://reader034.fdocuments.net/reader034/viewer/2022042401/5f101a437e708231d4477534/html5/thumbnails/24.jpg)
Show Notes: http://www.superdatascience.com/177 24
code a random forced algorithm in R by the end of the
year." That's gonna be your result but then what's the
purpose? It has to be emotional, it has to be like, "So I
can actually help prevent cancer and save lives of
people, lives of people in Idaho, or in other places."
Zach Loertscher: Sure.
Kirill Eremenko: Yeah. And so the M is the Massive Action Plan, that's
something to look up the Rapid Planning Method by
Tony Robbins, it can help you with the organizational
side of things. The reason why I was bringing this up
is because, "have a goal in mind", that's the first part
of the RPM, have a vision where you're going because
unless you have that, it's really gonna be hard to be
disciplined. Discipline is a micro thing, it's within a
day, within an hour you have to be disciplined, but
you can't achieve micro effectiveness without a macro
vision, without a macro goal in mind because where
are you going, right? You might be disciplined for an
hour, for a day, for a week, or a month but then you're
gonna be like, "What's the point of all this? Where am I
going? What's the purpose?" And you're gonna lose
motivation. So that's another thing.
The first image that pops to mind when you ask about
discipline is, when I was working at Deloitte and also
at the same time building these first courses I was
grading, just every 15 minutes I had a timer going off
when I had to write down, did I spend those 15
minutes effectively and were they good 15 minutes or
were they bad 15 minutes? Did I waste them looking at
Facebook or YouTube or whatever? And then I was
tallying them up for the whole day.

Kirill Eremenko: We have some people on the team that actually use it
and it works exactly like that, every 10 or 15 minutes,
whatever, it goes off and you have to write down what
you did. You just have to be very strict with yourself.
Another good saying I heard is, if you want to be an
entrepreneur, a successful entrepreneur, you have to
be the harshest slave driver for yourself. It's not about
bossing around other people, it's about bossing
around yourself and not letting yourself rest. Like all
right, you rest when you can, but yeah it's important
to be very strict with yourself. That's what I was-

who's listening is taking notes 'cause this is awesome.
Kirill Eremenko: This is a fun podcast, it's like all of a sudden a
reversed situation. All right, well let me ask you a
question then.
Zach Loertscher: Sure.
Kirill Eremenko: You mentioned entrepreneurship, and you're in
healthcare and data science, do you think that data
science is a good space for entrepreneurship? Or is it a
space where you solely should focus on building a
career and progressing up the career ladder?

Zach Loertscher: That's an awesome question. I haven't been in the "real
world" yet, so I'm still finishing up my degree and
everything. So take my response with a grain of salt,
but I think that the data science field is probably the
best field to be entrepreneurial in because it has
everything set up for it on the internet. Everything that
is popular is opensource, everything that you'd ever
want to share can be shared and is being shared and
people are consuming it. If you're wanting to build
your brand or your business or whatever it is, data
science is probably one of the best fields for it right
now because if you think about it, for other fields, not
a lot come to mind at this moment. I don't know what
it is about data science but it's really taking off online.
Since that's the future of our society, is this
collaborative, cohesive societies, I think it's probably
one of the best fields.
Kirill Eremenko: Yeah. Yeah, no. That's very cool. You definitely can
connect with the right people apart from the resources
Amazon Web services, or [inaudible 00:42:23] SQL,
and all these tools, Python, I think they're a [inaudible
00:42:27] tool, all these online tools and datasets. The
other thing is that you can connect with the right
people to build this team, or even international team of
Data Scientists and make things happen. That's what
Kaggle's all about, right? They have some projects
where you can participate as an individual Data
Scientist but there's some projects where you're just
not allowed to participate, as far as I remember. You're
not allowed to participate as an individual, you have to
be part of a team, right?

Kirill Eremenko: And I think that's a really cool concept.
Zach Loertscher: Yeah, it's awesome. And something else to note that
I've noticed, I've been pretty heavily in the job search
for the past few months and something that might
make the entrepreneurial route more appealing is it
takes a very long time to set up the data infrastructure
required to really have a good functioning data science
team. And you can correct me if I'm wrong, but to have
your data warehouses all set up and normalized and to
have your data capturing processes all automated, if a
company just jumps on the data science train and
hasn't done any of that prep work and you were hired
by that company as a Data Scientist, you might find
yourself in a situation where, "I'm just not doing what I
was expecting." Right?
Kirill Eremenko: Yeah.
Zach Loertscher: So, that might make it more appealing as well 'cause a
lot of companies are still making that transition right
now. I put a post out a couple months ago talking
about this and it got really good response as well.
Talking about this, how every company is at this
different stage of their data evolution. Some companies
are towards the backside of things, they're doing
everything in excel spreadsheets and email and other
companies, they have all their data is all distributed,
it's all in the cloud, they've got realtime reports going,
they have realtime models running and making
decisions. So yeah, when you're comparing the
entrepreneurial side of things to the company side of
things, the entrepreneurial can be a little bit more

appealing in that sense. You get a little bit more
control over what you're doing and maybe you don't
have to wait so long for a lot of those things to happen
right now.
Kirill Eremenko: No, that's definitely a good point. The difference is or
can be, it depends on how you set up the
entrepreneurial side of things but let's say if you're a
Data Science Consultant, difference is you only need
the tools that you actually need, that you are used to. I
hear you use Python and Excel, or Python and SQL, or
the combination that you like, Python/Tableau/Excel
and you set them up for yourself and then in any
business you go and you're like, "All right guys, I'm
here. I can help you out with this specific type of
problem, here's my rate and give me your data." They
give you their data, you take it back, you upload it or
even if you use it through their tools, you can make
sure that they've set ... if they don't have it set up and
if it's going to take a long time, you just move on to the
next line.
Either way you do it, you have those tools in your
arsenal and you perform the analytics and that's it,
that's all you're worried about. You're not worried
about all the red tape, you're not worried about
waiting for approvals and so on and so on. You have a
plethora of choices of companies that could be your
potential clients because ultimately any business has
data these days, you just need to show them that you
can add more value than you're gonna cost them,
that's it.
Zach Loertscher: Right, right. Absolutely.

it's about not charging the client until they see value.
So as a consultant or a Data Scientist ... and that's a
starting point for a data science entrepreneur, you
being a consultant, you can go into other spaces later
on, make great products and stuff. But there, to get
started as a consultant, you say, "Hey, I can add
value, I'm not gonna charge you anything, I'm gonna
do this project on my weekend." You do the project
and then you say, "Hey, if you like it, you pay me. If
you don't like it, that's okay, you keep the results and
no problem." At the end of the day, if your project
added ... I don't know, let's say it's a business that
makes $100 thousand dollars a month and you just
added 10% to their bottom line, you added $10
thousand dollars every single month, from now on
they're gonna save $10 thousand dollars.
It's pretty obvious that they're gonna be okay with
paying a consultant like that, a certain amount that is
around the $30 thousand dollar mark or $50 or
whatever.

Kirill Eremenko: Okay, all right. Let me ask you another question. What
is your favorite part about data science?
Zach Loertscher: My favorite part of data science. I think I'll go back to
when I really discovered it, I think the most exciting
part for it, of data science for me, and it still is, it's just
the idea that you can give power to a system to make
decisions. Does that make sense?
Kirill Eremenko: Mm-hmm (affirmative).
Zach Loertscher: In my mind, I mean, maybe a lot of people don't think
that's exciting but for me it's really exciting. I think
that, that's just an amazing thing because I've worked
at places where decisions are made by gut feelings or
people maybe don't use the data to the fullest capacity
that it could be used to. But even taking it a step
further and saying, "Look, the data, we can use this
and harness this to tell us things that we could never
find out otherwise.", is really exciting for me. The other
part that I think is really exciting about data science,
is I love the data visualization part of it. I love being
able to take something that's hard and coarse and
rough as math and numbers and put it to a visual that
people can understand and digest and really gain
insights from. Those would be probably my two
favorite parts. Sorry, I know you asked for one and I
gave you two.
Kirill Eremenko: No, no, that's cool. No, that's good. Yeah, no, I like
that. I like that you have at least a couple of things
that you're super excited about in data science and
definitely a very diverse field where anybody can pick

sense that they have their own preference, they might
be excited about the data preparation part, or
identifying the challenge or the problem, or talking to
clients and things like that. Totally normal, totally
agree with that.
Zach Loertscher: Absolutely. What about you?
Kirill Eremenko: For me?
Zach Loertscher: Yeah.
Kirill Eremenko: What's my favorite part of this, nobody's ever asked me
that question.
Zach Loertscher: It's hard to choose.
Kirill Eremenko: Yeah, I know, it's hard to choose. I think for me it
would be breaking down the complex into simple, it's
that part where I know the insights, I know what I
found. Now, how do I explain it? How do I make these
faces of my audience light up and see in their eyes that
they have passed through a threshold concept, for
instance. A threshold concept is once you learn
something, that's a threshold concept, you never see
the world the same way again, right?
Zach Loertscher: Yeah.
Kirill Eremenko: Like, "How do I make sure that they understand this
and they can apply it and they can make their
businesses better?" And so, that's probably ... again,
just like you, I probably have a couple. That one and
the other one would be the whole investigation
process, the whole digging to find the insights. Once
you're in the project, you really with your heart and
soul in the project, it's really fun. You can get lost in

the project that time will fly by, you know that feeling,
right?
Zach Loertscher: Yeah, yeah, totally. Yeah. Yeah, you can spend a lot of
time in the exploration phase but it's just 'cause it's so
exciting and fun and new and you never know what
you'll find.
Kirill Eremenko: Yeah, for sure. What's your least favorite?
Zach Loertscher: My least favorite part.
Kirill Eremenko: Yeah.
Zach Loertscher: I'm gonna go out on a limb here, I know a lot of people
get into Data Scientist from a developer background so
maybe I'll get a lot of flack for this but probably the
programming, that's gotta be my least favorite part.
And maybe it's also because I'm coming from a more
business analytics side of things where I want my tools
to be on AGUI and nice and easy to use. I don't like to
worry about the syntax or spend forever on google
finding things. That being said, I realize that there's so
much power in being able to have control, exact
control over your data, over your project and your
work flow, but you really can't have inside of AGUI, so
something like, I don't know, Tableau. It's an
incredible tool but at some point it has limitations, or
excel, it can be hard to automate sometimes. That's
probably my least favorite part, but I recognize that,
that's also one of the most powerful parts too.
Kirill Eremenko: Yeah, gotcha. I agree, I like programming but I don't
like the getting lost in the specifics of certain
algorithms.

Show Notes: http://www.superdatascience.com/177 33
Zach Loertscher: Yeah.
Kirill Eremenko: Sometimes you gotta remember to add this line, you
gotta remember this part of the algorithm, and this
hyper parameter, the tweaking of these statements.
So, I like creative programming when you can just
come up with stuff and make things, like even you're
writing your own algorithm. That's really fun, you're
writing something that's ... but sometimes when it gets
too mechanical and you forget something, the
debugging of the code, that can be quite tedious.
Especially if you forget or you don't notice that there's
an error in the code, not because you're approached,
but just because you forgot something that's part of an
algorithm. Definitely then that can be a bit tedious.
Zach Loertscher: Yeah.
Kirill Eremenko: Yeah, that's what I'd say.
Zach Loertscher: And to anybody who's listening who's maybe at the
initial point of this learning curve, for me, that
learning curve's been more of a brick wall that I
haven't really climbed up it, I've more smashed into it
as much as I could until I finally have broken through,
at least a little bit I think. If it's hard for you, it's been
hard for me too, so don't worry.
Kirill Eremenko: Yeah, yeah. Well, yeah exactly. At the end of the day, if
somebody really doesn't enjoy programming, there's so
many other ways you can be a Data Scientist, even
without programming. Like you said, there's so many
great tools like Tableau for instance, where it can add
so much value programming a single line of code.
Zach Loertscher: Yeah, absolutely.

Show Notes: http://www.superdatascience.com/177 34
Kirill Eremenko: Yeah. Okay, well let me ask you one more question
before we wrap up. What career aspirations do you
have? I know you're in the health industry now and
you're starting out as a Data Scientist, is there
anything you're aspiring towards? You want to be a
Chief Data Officer, or Chief Data Scientist? I don't
know, do you want to maybe have your own business
one day? Or do you want to be an executive, like a
Chief Executive Officer that uses data science? I don't
know, I've mentioned a few executive positions, I don't
know why, maybe there's other roles that you're more
interested in, but what's on your list of aspirations?
Zach Loertscher: I would say I'm pretty easy to please, I don't really
aspire to super, super high level positions because I
want to always maintain a good work life balance. I
never want my work to become more important than
my family or taking care of my wife, whatever it might
be. So I'd say the biggest aspiration for me is just to
find a position in which I get to do data science and
also maintain that all in balance. And maybe that'll
involve some give and take with things like pay and
salary, but that's ultimately my goal because I feel
there are a lot of things in life that bring happiness
besides prestige or position or money. For me, the title
isn't super important as much as the work life
balance. And also, is really important, is the people I'm
working with. Are they collaborative? Are they excited
to be at work? Or is it a team that just shows up and
just does what their told and then goes home, you
know what I mean?
Kirill Eremenko: Yeah.

Show Notes: http://www.superdatascience.com/177 35
Zach Loertscher: Those are probably the two most important parts for
me, the title can come later I think. That would be my
highest aspiration.
Kirill Eremenko: Gotcha, gotcha. Fair enough, that's a very fair answer
and it's good to hear you got your priorities sorted out
in a nice way. Okay, well Zach, thank you so much,
enjoyed the new kind of format of this episode. Before
you go, where can our listeners contact you, get in
touch, follow you, learn more about how your career
progresses?
Zach Loertscher: The best place is LinkedIn, so just look me up on there
and connect with me, I won't reject you, I promise. The
listeners of this podcast are great people, I'm sure, as
well as everyone else, so that would be the best place
to get in touch with me.
Kirill Eremenko: Gotcha. All right, and Zach's got a very interesting
spelling of his surname, so we'll include the link to
your profile on the show notes, people can connect
with you there. Okay and one more question for today,
what's a book that you can recommend to our listeners
to help them enhance their career?
Zach Loertscher: It's not necessarily a data thing, okay, it isn't a data
science book and maybe it's been recommended
before, but I love the book, How to Win Friends and
Influence People, by Dale Carnegie. It's a little bit of an
older book but it is probably one of the best books
about forming relationships with people and really
learning how to, I don't know, not just win friends and
gain influence, but really, I don't know, build those
relationships. Because that can be one of the most
satisfying parts of your work, of your life. Even when it

comes to the data science part of things, it will help
you with communicating things like Kirill has
mentioned earlier, breaking complex things down to
make them simple and making you less of a robot and
more of a human, if that makes sense. That book has
had a big influence for me and I hope that anyone
who's listening goes out and reads it, it's awesome.
Kirill Eremenko: Definitely, fantastic book. I also recommend it and it's
come up three times today.
Zach Loertscher: Oh really?
Kirill Eremenko: Yeah, definitely worth picking up. All right Zach, thank
you so much for coming on the show. I hope our
listeners enjoyed our chat, I definitely did, it was a
nice, pleasant conversation and I think there's quite a
bit of value. I definitely learned a few things from you,
thanks so much.
Zach Loertscher: Yeah, I learned a lot from you. Thank you so much for
having me on the show.
Kirill Eremenko: There you have it, that was Zach Loertscher, an
aspiring Data Scientist and we discussed quite a lot of
different things. Hope you enjoyed the show, and a bit
of a different format this time where I answered a few
of Zach's questions. My favorite part probably was
when Zach talked about the way he goes about or the
way he thinks about selecting an industry to get into,
that it's important to speak to someone who's already
in there, or who got into there recently or is getting
into there. So that you can get their perspective, you
get some insider knowledge about that industry and
you make the right choice about your career.
