Let's do the math on that. 60 hours is twelve hours a day, plus three more with your daughter. Add a couple of hours for showering and dressing, food prep, and general housework. That's seventeen hours a day, leaving seven for sleep plus zero for exercise, recreation, social life, career development, etc. Oh yeah, and interaction with your wife too. Maybe that's working out for you, but I know where it would lead for most people: physical, mental, and emotional exhaustion in only a few months. Even if that three hours a day with your daughter is merely being in the same place but doing other things, the weekends - which you claim you spend with her as well - wouldn't be enough to recharge. Of course, that's the optimistic case where you have a spouse who does many of those things you apparently don't even think about, and who is willing to accept your devotion to company above family. In reality, that's not likely to last long and you'd be single in short order. Some would say that proves the point about startup/family incompatibility right there, but let's say you overcome the strong anti-male bias in our family-law system and become the custodial parent so you still have a family (sans wife). Now you'll need to spend even more time on food prep and housework, plus other tasks related to school or general care and feeding of a child. Also, many of those tasks will need to be done at particular times, not at leisure. Even if you slept a mere four hours a night, you'd be hard pressed to spend three hours a day of real time with your daughter. In short, then, I just don't think your example proves your point very well at all. Maybe you're superman, the one in a million who could sustain such a schedule. That still says nothing about whether others can.
