I've been doing startups since I was 18 years old, for over 15 years, and so my social circle is reasonably well populated with other startup people --- mostly men, for obvious reasons --- and this sentiment is so not gender specific that it's hard to see how it's even germane.

Everyone gets ground down by trying to get small companies off the ground. I don't know many people at all who think 90(!) hour weeks and death marches are a good idea, even at launch time.

Stop smoking, though. It's really bad for you.
