I do this exercise any time I feel like I'm similarly stuck:
- List all of my current projects
- List what status they are in
- Make notes about them (an elevator pitch, a slightly longer description)
And then, as silly as this sounds, I read through the list and see what I would feel bad about not doing.
Anything that I want to do stays, anything I don't want to do goes on another list for me to re-consider at a later date.
I do it about once a month.
I think part of my problem is that I bounce between projects that I think are most important and others that are more achievable :)
I tend to fill the gaps in my time/budget/knowledge with small projects that seem doable but now even the small ones are dragging..
I think I just need to finish something for a change.
