There are often posts on here showing that it is better to spend say 10 or even 5 years doing 35-40 hour weeks at a FAANG where your total comp will end up being $2-5,000,000 over that time, than risk it at a startup working 80+ hour weeks for a chance at the big time but ultimately leave with nothing apart from exhaustion and an unheard-of failed startup on your resume.
I think there is a lot of truth in that.
And yeah I went to school with a bunch of kids who had semi-success as a teenager at sports or music, only to then not make it big when they needed to at 16 or 17 etc. Perhaps they all ended up at successful unicorns or are L7-FAANGs, but I doubt it
