Day One: You write 2000 words, witty sentences, keen observations, actually interesting to reread. This is going to be great! I might actually sell this thing!
Day Two: Realize you've used up all your good ideas on day one. Slog through threads of plot chronologically. Character seems boring (and too much like you). Realize you have very little dialog. Maybe it's literary fiction? Or weak writing. Still, 2000 more words down.
Day Three: Keep saying all day (to self) that you are going to spend your 2-4 hours adding dialog. End up with zero words as of 8:15 pm. It actually seems like a good day to veg in front of the TV with some Golden Graham cereal. But, no. Is it too early to go all meta-fiction and start writing about your process in the novel? Probably.
I feel weirdly good, though. Physically good. (That should probably be "well" as in "physically well" because I don't think my ability to discriminate texture through my skin has changed.) Can writing actually heal? I think it can. Off to knock off another 2000. Or 1000, since I'm ahead, right?
