I'm 43 now and you couldn't pay me enough to do several things at job now, like working saturdays (normal here in mexico), working from an office, doing death marches and whatnot. But, I did all that and more in my 20s as IC and 30s as a leader. I helped 3 startups go up and now 2 of them are unicorns (That was pure luck but doesn't change my view). My point is, there is a time for everything. I've hired a couple of JRs at my startup nowadays, and I tell them: what you lack of experience, I want you to cover by will. Guys at 20s want to eat the world. The energy and motivation is amazing. Those are the years to run and hustle like a demon. However, I would never do that in a big Corp environment (like Goog, IBM, MS, etc) because you will only be abused by middle manager. But as 1st, 2nd or 3rd engineer in a startup. I'll do it all again.
