This presumes that all 24/7 startups are working 24/7 because of the "swinging for the fences" idea - because they need to rush to build something before someone else does - and that they aren't doing so because they think it's the only way to work. While some 24/7 startups are 24/7 because of a true need, surely some amount must also think they need to work in perpetual crunch mode because "that's just how startups work"
