When writing my first manuscript, I came across a great article by Holly Lisle, titled: "One-Pass Manuscript Revision: From First Draft to Last in One Cycle." Instead of doing spotty revisions chapter by chapter, you savage the whole book in one go and create a masterpiece - or that's the theory. I've taken bits and pieces of Ms. Lisle's advice for other projects, but since my NaNo novel is exceptionally... exceptional, I think I'll follow her process from start to finish and see where it takes me.
So good luck to all NaNoers. We're halfway there!
