I think this is true for the most part, although poor development practices can eventually catch up to you (I once worked in a place with 5000 programmers working on the same thing and whose productivity averaged 1 line of code per day -- it can happen.. :-P ). However, while many people will rightly complain about stress in the workplace and long hours coding, I'd like to also point out that stress and lack of sleep can come in a variety of packages. I've seen good programmers destroy their careers because they thought there was no problem staying up drinking all night on workdays. I've experienced (unfortunately) being in a bad relationship and arguing with my SO all night until it was time to go to work. Stress and sleepless nights will cost you in your career. It might cost you a lot. It's not sexy to be the person that avoids drama in their life and manages their sleep schedule well, but it can have pretty significant rewards. If you think that in SV the difference between a top and middling performer can easily be in the $100K per year area, it puts a pretty hefty price tag on "Oh, I'm pretty sure I can catch up on my sleep on the weekend". From the "hard to talk about, but I wish I knew this 20-30 years ago" department :-(
