After some time working in "start-ups" this is one thing I agree with more than anything.<p>"Hours
While people occasionally choose to push themselves to
work some extra hours at times when something big is
going out the door, for the most part working overtime for
extended periods indicates a fundamental failure in planning
or communication. If this happens at Valve, it’s a sign
that something needs to be reevaluated and corrected. If
you’re looking around wondering why people aren’t in
“crunch mode,” the answer’s pretty simple. The thing we
work hardest at is hiring good people, so we want them to
stick around and have a good balance between work and
family and the rest of the important stuff in life."
