I believe it depends on the atmosphere of your full time job. I've been working on my current project for the past 2 years now and have had 2 different full time jobs in that period. My previous job had me working at 120% of utilization, with a bunch of overtime. Needless to say, not much of my side-project got done. When I got home from work every day, I wouldn't even think about touching a computer. My current job isn't nearly as stressful. Although I get a lot done, I still salivate about programming when I get home. I think it all depends on how much of a workload you can handle past your full time job and how stressful your full time job is. Having positive and motivated people at your full time job also helps your motivation on your personal project.
