I wrote 2500 words this weekend, which exceeded my goal. I'm on what's probably the last scene of the draft. I should be exultant but in fact am just exhausted. I know once the draft is done I have to go back and heavily edit the beginning, which is slow and meandering and doesn't do nearly enough in the service of the story's main relationship. Right now I can't figure out how I'm going to do that. It seems an insurmountable problem, a big hill of slippery mud.
Once I get started on that, it won't be quite as bad. One thing at a time usually works, at least at first.
It's got a due date. Therefore, it will be done by that date.
