> And he is the most impressive CEO in this generation, perhaps in history, so long hours must work for some people.

Even if we assume the first statement is true, which is a big if, it still doesn't necessarily support the idea that working long hours is good. After all, you can't tell whether he was successful because of, or despite the long hours.

I think there's something to be said for the nature of the work you are doing. If you absolutely love what you're doing, you can burn hours long and fast and hard. I think Elon gets his head wrapped around a problem and just eats lives and breathes that problem to the point that the long hours are natural. I've been there on stuff, where I have to fight to tear myself away rather than fighting to keep myself doing it. The latter sucks and will destroy you quickly, but the former isn't so bad for the psyche.
