I'm in a similar situation to you, I work 40 hour weeks, maintain a demanding relationship with my girlfriend, freelance in my spare time and still fit in a couple of hours a night for my private projects.
More needs to be discussed about this group of entrepreneurs. So much emphasis is put on the full time, no-expenses-or-responsibilities-whatsoever early to mid 20s male entrepreneur s, but I think there are probably a lot more entrepreneurs like you guys.
