Lot of great stuff on here. However, here is the thing that worked for me since I was in the same boat as you: after finally releasing a project into the world and calling it "done", I felt SO much better than when I jumped from project to project every 1-2 months. Finishing a project is a different sort of "high" that I want to get again and again. My advice would be to pick something small so you can finish it and have that experience. I now have two out of work successes I can point to, and more importantly I now feel guilty wasting time on side projects that aren't a part of my third release I'm working towards!
