I'm talking about startups (groups of individuals), not individuals. I agree that it's objectively pretty daft for a person to bleed out of their eyes for 90 hours/week for a startup (other than short bursts that are sometimes necessary). But is it daft for a startup, in its first 3ish years, to encourage that behavior? And, does that that behavior meaningfully improve the startup's chances? Personal health aside, it seems pretty clear that excessive work hours correlates with startup success. I've never met a founder who has hit a financial homerun that did it working healthy hours. see points 2&3 here: http://www.paulgraham.com/really.html http://www.paulgraham.com/really.html
