Yes. And "having a life" is overrated, as was noted already. I work 4-5 hours a day on a startup project, and another 4+ on a "real" job to pay the bills.

However, I still find plenty of time to spend on things other than work, whether it be personal project/hobbies/self-improvement, or hanging out with friends. So I may or may not have a life, depending on what standard you're measuring by. But I'm happy.
