Yesterday, worked on a section in the tough part, but toward the end slipped into trying to make the characters' actions and words fit the plot. So today I skipped ahead to what used to be the first chapter, but now is about 80 pages in. There I have been trying to write what the characters would do, not what I need them to do. Thus I now see the entire middle slipping away, joining the end that already slipped away, leaving me with a ms that no longer has even a skeleton of a plot to follow.
