Are you hesitent to take on new projects now? Part of the reason I kept trying was a resolution to finish my projects.
I do a lot of small projects here and there. I'm currently working on one that I've been chipping away at for the last six months or so, but it's coming along at a much more relaxing pace.
While I do think that it's important to finish what you start, I also believe that knowing when to stop is just as valuable.
