I also have a full time job as developer. I don't have kids, but I live with my GF which is almost as being married when it comes to having time for each other. Fortunately for me, my girlfriend works as a nurse and has lots of afternoon/night shifts, which is great for me so I can dedicate myself to some pet projects. However it's not easy, it's very complicated to explain to her that "I don't want to go out because I'm working on this bug...". So you have to balance your life a little more, instead of taking 2 months to complete your project, maybe it will take 3 months. And that's fine for me. Some times can be a good thing to get away of your project and come back a week later with a fresh mind, it makes you actually want to work. With that said, after 6 months with lots of interruptions including holidays I was able to complete my app http://codebugapp.com/ http://codebugapp.com/ , I just released last week.
