I think the other part of it is that even if you can be the best at something, there's an enormous opportunity cost to that. We look up to Olympians, but it's tough to fully grasp the amount of sacrifice it takes to win an Olympic gold. You're not going to have a normal social life or other hobbies - you're just doing your sport (or related practice) for as many hours a day as you can without sustaining injuries that would impact your ability to train more.

Same thing with the best musicians, lawyers, researchers and a whole lot of other professions, particularly those that we hold in high esteem - there are a lot of people who want to be at the top, and you can't stop to take a break because plenty of those people will be working more while you rest.

I'd rather be good at a bunch of different things and have enough free time to read a book or play videogames on the weekends than be extraordinary at one thing.
