I find new inspiration when I edit my stories bit by bit. Also, maybe an outline is not what you need. I never use an outline. My story writing is pretty stream of conciousness with a few things pieced out specifically ahead of time. generally, I know the ending - the specific wording, even - I have a specific scene I really want to put in and I have a couple of rough ideas. Getting there is usually an adventure for me. Then, sometimes, the ending takes a complete turn from the original plan.

Try different methods. Throw a bunch of shit on the wall and see what sticks.
