Why are non-work interests important?

You can be addicted to improvement in such a pathological way that there's nothing else in your world than just improvement on a single track. That, too, I rejected quite early on both in life and my career. Again, acceptance that we're never going to be number one, not interested in chasing it. But I'll be good at a lot of things. You can become good at a lot of things if you don't allow one single pursuit to dominate everything forever, which again comes with that trade off that you're not going to be the best. There's only going to be one Michael Jordan.

All he did for that period of time that he was active was freaking go to the court and shoot baskets, right? The whole life and everything around was optimized for that. And I've gone, "I don't want that." I want to be good at running a business, so I'm going to do that diligently for about 40 hours a week. Then I'm going to spend my weekends at a race track, or traveling, or with my family or friends, or any of these other things that provide in my assessment a well-rounded existence that is something where, if any one of those individual things should falter, the business starts going sour or I can't progress in my racing or whatever, I have other legs to lean on here. It's not going to be the only one. I'm not going to tip over just because there's a single pursuit in life or single factor of my existence that if not falls apart, then falls sideways.
