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.
