When I worked at SpaceX, I slept in the office a handful of times. It wasn't out of an apparent obligation to work long hours, but because I was indeed doing something awesome at the time, like remotely flying a space ship. Of course, Elon Musk's expectation was for everyone to work themselves to their limit, and he praised the folk putting in 80 hours per week. I myself found success in confidently maintaining a sustainable work-life balance, and never felt pressured to work longer than I wanted to.
