Having a similar problem myself, I can only offer things that I've tried myself in the hopes that they might help you, too.
I don't think my NaNo experience will help in this case, since you have a complete draft already... that was always my big sticking point. I'd go back and edit the beginning before I ever got to the end.
Maybe you could set yourself a deadline? Or a "one more pass, straight through, then send it out" resolution? Or some sort of challenge suited to what you want to accomplish. That worked for me - I have a complete first draft now, courtesy of the NaNoWriMo challenge, which I'm fairly happy with and am working on my first editing pass to whip it into shape for submission.
One thing to remember, too, is that publishers have editors. It's their job to help you out with editing - it's your job to get their attention. And you can't get their attention (and help) if you don't send it out!
Ok, I should talk, I haven't submitted anything (aside from k5, who can be rather vicious in their rejections...). I'm working on a few things though... :-) -- Who needs to be big and burly when you can just apply physics?
And I know exactly what you mean about not having to deal with rejection... as long as I haven't submitted, I can console myself with the thought that I'm a much better writer than most of the stuff that's published. :-) -- Who needs to be big and burly when you can just apply physics? [ Parent ]
