I just fixed a massive problem in my chapter-in-progress by having a character do exactly the opposite of what I had them doing before.  Also by remembering that a chapter should have four or five purposes if I want it to be compelling, not just one.  And also remembering that (as my husband pointed out) several of my characters have complex relationships with each other in addition to their complex relationships with the main character, and should act like it.

I like the changes.  I think they work.

Happy happy happy.
