The Power of Mentorship
Joe's Nerdy Rants #58 - Mentors matter, plus weekend reads and other stuff
When I first got into the data field decades ago, I often heard about things called “Inmin,” “Kimbowl,” and “data warehousing.” Frankly, I didn't think much about those things at the time. My background was in math and stats, and I was more into programming in Matlab. I begrudgingly accepted the Lord Savior Excel into my life. At some point, I found data warehousing. I just figured it was another place to plop data, do analysis, and make some neat graphs.
A few years ago, a friend introduced me to Bill Inmon. By then, I was very familiar with him and his contributions to the data industry. I flew to Denver to meet Bill, and we hit it off immediately. It turns out we’ve got a very similar background. We are math nerds and have spent time in El Paso, worked on ranches, etc. This turned into a strong friendship for both of us and mentorship for me (I teach him new things, but it’s very disproportionate to what he teaches me).
This week, I was supposed to be at AWS re:Invent in Las Vegas, which is only a 50-minute flight for me. However, that wasn’t in the cards (bad Vegas pun). This Fall, I traveled the globe, attended conferences every week, and met many people. So much so that I was exhausted. I needed a break from crowds and wanted the company of close friends, so I decided to visit Bill instead. Every time we hang out, we chat nonstop for hours. In this case, days.
Bill’s been programming since 1965, has significantly contributed to the computing field, and has known many of the legends of our industry. Along the way, he also became one of the legends himself with his contributions of the data warehouse and ETL, among many others. I can argue that without him and a few others, the data industry as we know it wouldn’t exist today. I’m grateful I have Bill as a close friend. His advice has helped guide my career. And it’s crazy. If you were to ask me when I got into my data career if having Bill as a close friend was on my bingo card, I’d have laughed. But here we are. Today, Bill is basically my big brother.
More broadly, my friendship with Bill got me thinking about the importance of mentorship. I’ve had other mentors over the years. Back when I got into rock climbing, people like Todd Skinner and Paul Piana were there in my hometown of Lander, WY. They were the first people to free the big walls in North America and elsewhere and are some of the most badass climbers ever. Climbing with them helped accelerate my climbing skills and knowledge. I’ve had similar experiences in DJing (thanks to Steve Santoro (Bam Bam), John Creamer, and many others) and my early career (thanks to Dennis and Mitch, among many others!).
No matter the stage of your career, mentorship is essential. You’re going to make a lot of mistakes. Find someone who can guide you in your career and show you the ropes without judgment. Learn from their success and mistakes. This should be a friendship, by the way. I see some people offering advice on a pay-to-play basis. That’s advice, but it’s not mentorship. Mentorship is provided on a non-transactional basis. People mentor because they come from a pure place of paying it forward.
But understand that a mentor also has to find you worth mentoring. There are different levels to this. A mentor wants to mentor people they feel are capable of rising to a certain level. In most cases that I’ve seen, a mentor feels you’ve got the potential to carry on from wherever they are. The top expert won’t likely mentor a complete newbie. There’s just too much of a gap at that point. You need to be at the level a mentor will find you respectable and capable enough to be worth their time investment. This usually means being close to their level or at least having the potential to get there with hard work, grit, and listening to the mentor’s advice. Iron sharpens iron, as the saying goes.
How do you find a mentor? They’re everywhere. You probably know one right now. Find someone who’s ahead of where you want to be and whom you admire. In the case of Bill and I, he’s light years beyond, but it’s not a contest. He’s also way older than me and started his career before I was born. Just find someone who will take you under their wing. They’re out there.
Finally, if you’re experienced in your profession and can give back to the world via mentorship, please do so. It’s very rewarding. I mentor a handful of close friends (sorry, the door to more people is closed for now). It’s a chance to show others the obstacles I saw and either avoided or overcame. And it’s a chance to help the new crop of people get to where they need to go.
This is also why I’m moving toward education. It’s the classic 1:1 vs 1:many solution. I choose the latter at this stage in my career. Helping as many people as possible with skills and knowledge is very important to me. And I’m just getting started. Stay tuned for details early next year :)
Finally, thanks to everyone who took advantage of the Practical Data Modeling holiday sale. It means a lot, and you have much to look forward to!
Thanks, and have a wonderful weekend.
Joe

Please note: I've traveled a lot for the last few years—probably too much for a person to stay sane or healthy. I tried to figure out how many times I’d traveled the globe. I have no idea. It’s a lot. And…
In 2025, I’m reducing my travel. For one, I'm hyper-focused on a new company I’m starting (stay tuned for details). I also want to spend more time with my family and get outside in the Mountain West. I live in one of the most incredible places on the planet and never see it. Nature calls.
Same as it always was, I only accept workshops and speaking engagements that meet my fee requirements, except for rare exceptions (we’re friends, you’re not charging for tickets, etc). You’re working hard on your event. So are the speakers. Let’s mutually benefit each other. If you’re making money, pay the speakers too.
With me, you get what you pay for and then some. You'll get a ton of enthusiastic attendees and a very entertaining and informative talk/session. Your event will be on the global map. My track record speaks for itself. Please submit a speaking request if you want me to speak or give a workshop at your event.
Thanks! If you want to help out…
