The startup is my baby and I'm solo. I don't just develop, I design, market, handle investor relations, etc. I wouldn't do this if it wasn't this specific situation.
Edit: Haven't had a girlfriend or dated or regularly socialized with friends in years, but I don't feel bad about it. Most of my friends who I respect the most are just as busy as I am pursuing their goals in music and neuroscience. :)
Edit2: I do hire additional devs when I can afford it, but that doesn't have an effect on my hours.
I wake up and work until I go to sleep. Every day. 8 hours of sleep, either in one chunk or in two (biphasic). I feel better with biphasic. So that leaves 13 hours each day after subtracting eating time, housekeeping, bathroom "tasks", reddit/HN, and falling asleep transition time. 91 hours per week. Been living like this for years without burnout, although I think at 100-130 hours one is asking for trouble.
