That's a good point. It sucks to work overtime constantly when you had other plans, commitments, etc, especially when the bosses are ungrateful.
On the other hand, when working on something that you know upfront is going to be an enormous challenge, and you really love what you're doing, the hours don't seem to matter. The problem for me becomes more of a physical thing. I can work a 70+ hour week or two, but then it takes a week to get back to the same level of output.
