Nanowrimo

I wrote a novel in November and I've been having trouble finishing it.  In July they do campnanowrimo which is much the same, but you can adjust it to a smaller goal if you like. I really wanted to do it, but I don't like the idea of starting over without finishing the other. Namely because I NEVER FINISH ANYTHING.
So I am going over it top to bottom and hoping by the time I reach the end I can think of how the full ending will be.
