NaNoWriMo: Insert copious swearing here

So normally when I don't write these days it takes the form of goofing off on the internet when I should be writing. When I actually start writing, I do fine. Not today! One paragraph. Then stuck. This does not happen to me. But I am annoyed with myself for never getting anywhere at all with this thing, so I'm determined to keep trying for another few days at least.
