I'm at 2500 words already and I could call it a day easily, but this thing has already become an addiction--just a few more lines, a few more words, one more scene and then I'll quit. Really.
The compulsive quality is probably helped by the sheet of graph paper I'm using to visually track my word count, so I nudge myself to just a few more words to fill in just one more square and the next thing you know I've hashed out a paragraph.
It's . . . pretty crap, but I'm still enjoying writing it, and at least one or two good lines manage to slip through as I progress.
And I think I'm going to try and get just one more sentence in . . .
