My main reason for considering it is that a couple nights ago I thought of a terrific ending, but it would only work if I was able to make a compelling peak earlier in the story, and do some other character development that, in case I do continue, I would rather not divulge right now. Another problem is that I have a character and side storyline I really don't need, and I think it might work better without it, but I hate to cut out an entire character simply because my story changed paths from when I started it. And if I did so, I would also have to change the title. And then there's that whole problem finishing what I start.
I think writing fiction is far harder for me than non-fiction. My sister has more talent in fiction.
