I have a friend who worked his ass off as a teenager and had founded a moderately successful IT business from the back of his garage. He sold his share of the firm at 21 and walked away with a seven digit bank balance.
He’s one of those self-proclaimed alpha males who did a lot of stuff like playing video games a lot, martial arts (black belt in two martial arts), gym, partying, etc. He would also still work from time to time, not out of necessity but rather boredom
Unfortunately age and a nasty case of long COVID caught up with him, so he’s mainly going back into IT.
