I always found the hardest part of writing was the first few paragraphs...in a chapter or in a change of scenery. Anything like that.
I wonder how many writers have more than a "good enough" map when they start. I bet not that many. I have the outline of my novel in a notebook, so I basically know how it ends and all the highpoints...but my favorite parts are the parts I didn't even imagine before I started.
I don't know about you, but I discover characters take on lives of their own and demand to be written, so that changes the story as well.
You start in about two hours then, right? At midnight?
I can't outline. Just doesn't work. I'll stick with it for the first few pages, and then suddenly things go out of control. It's laughable, going back and reading the original plot summary or outline for a story I've been working on for a while. It's like the original message got horribly mangled in transmission.
My characters just don't behave properly. They act totally contrary to the original plot.
Midnight isn't for more than eleven hours here. Most of the other Hobbit Hole NaNoWriMoers are a few hours ahead of that - so it'll be eight or nine or so hours for them.
