What works for me is being able to toggle between a few different projects that requires slightly different skills and tasks. If I get stuck or tired of one, I can toggle to another project and still accomplish something.

Something else that works for me is letting go the guilt when I don't feel like something something (that's not urgent or time sensitive). If I'm not in the mood, I take a long break and allow myself to properly enjoy it without the guilt. This usually restores my motivation.
