Finish the book.
Don't worry about the length, don't even worry about the quality of the writing.
I was on such a roll for two years that it is a little disheartening to fall back to my more dysfunctional ways. It's all because I emerged from my writing fog and interacted with the real world. I know it couldn't be helped. It was going to have to happen at some point.
But I yearn for the innocence of those two years when I could daydream about what would happen without having to find out what would really happen. I have decided that most of the promotional distractions I've done have been fairly ineffective. (And I've done none of the really distracting things like conventions or signings.)
So I want to just get back to the steady writing and the steady finishing of my stories. I felt very empowered there for awhile. I'd like to get that feeling back.
Forget about the rest.
Get it done, and then write another and get it done.
