That is so false, and if it's true is unbelievably stupid. It means that your work is so useless you can do it completely sleep deprived and burnt out.
Wow, a great contribution to a company.
I'd think that a company that needs to perform at the highest level should do so with smart people giving their best hours and resting appropriately so they can be sharp.
The number of hours is irrelevant. Great people are great because their contributions are of great value, not because they contribute mediocre work three times as much as everybody else.
