Hobbies is probably not the right word, rather it's what they're good at. It just so happens that building a hobby makes you good at something. And this isn't necessarily in your control either. If you grow up on a farm you'll probably be very good at farming. If you grow up rich, you'll probably be great at networking and maybe sales. Some topics, domains, whatever make a lot of money and then a lot don't. If you're good at physical stuff then you're kind of fucked from a societal perspective. You chose wrong, or more likely got dealt a bad hand. If you're good at writing computer programs you got incredibly lucky. That's one of those topics that makes a lot of money. Some of this you can build and some you can't. My sister would never be a programmer because she hates it. But she loves kids, and she's a fantastic teacher. Unfortunately, teaching is a topic that doesn't lend itself to high pay. So that kind of sucks.
