It's not just your physical and mental energy that gets burned out through 12 hour days, it's also your passion. For all entrepreneurs there is a strong underlying passion burning inside and we push ourselves based on how brightly it burns, because we simply have nothing else to answer to. So if you're well-rested or highly caffeinated or adrenaline-filled with passion, you will be productive, because you're excited to. If you're pushing yourself to work 100 hours a week just because you think it's the right thing to do (this is the equivalent of face time in a corporate company) then you will be less productive, if not also resentful and discouraged. That's not to say deadlines aren't important, but work ethics should come from a desire within instead of from external pressure. I mean, we don't like the corporate world because of this external pressure, right? So why bring it with us to our startups?
