It sounds like you're worried that you aren't accomplishing things because you aren't finishing them. But really, I'm sure you're learning a lot while doing them, and that's accomplishment too. Many times when I do a project, I'm learning the most at the beginning, and the later stages are more fine details (that take a lot more time to get right, such as "productionizing" it). Feel free to stop working on things when you don't want to work on them anymore. At the very least, you have a lot of interesting things to talk about, and maybe even share your experience with other people (blogs, github). If you have diagrams or code, I'd suggest releasing them, even unfinished, because maybe someone else will want to pick it up, or just look over it. Even that can be a win, and make you feel productive / accomplished. Don't force yourself to do something that you aren't interested in anymore - maybe you've already accomplished what you were hoping for! Maybe you'll find something that you just can't put down - even then you might not feel accomplished because it's not your career. Even if it is your career, there's generally always someone who's better at it, and more you can learn.
