I was young and poor, if you're young and poor don't take the long shot bets. You need to build stability. Long shot bets will burn you out if you don't have a safety net (and living with your parents is a completely reasonable safety net, just unfortunately one I didn't have!). I wasted my 20s thinking if I worked 60+ hours a week for a startup I would be one of the lucky ones, and it was foolish.

As usual, there's no one-size fits all advice.
