I'm good at some stuff, and got there by practicing, but the stuff I'm great at* I got to through love. It's extremely effective, if you can accept the constraint on choice. You can (conditional on willpower) choose what to study diligently, but choosing what to love is harder, maybe impossible. *I speak amazing-for-a-gringo Spanish largely because I married a Colombian. I'm CTO in two places at once because I coded a lot of projects and learned a lot of languages for fun. And I used to play piano or guitar on average 4 hours a day, which paid of by making me good at it but in no other material way -- almost no money in particular -- so take that as an argument in either direction.
