Earlier quoted context omitted.
Was it intentional or unintentional that your comment also describes the life of entrepreneurs/startup founders?
The article described a life where interns basically stayed up for no reason. And if an entrepreneur is regularly pulling all-nighters for no good reason, he is probably doing it wrong. Sleep is worth its weight in gold, and you don't give it up for anything less.
I imagine most of us do it because we think it's for a good reason.
