The course on revision that I'm taking took me step-by-step through finding all my book's problems. Then it taught me how to break the book down by scenes (not chapters). I can see the wisdom of that now as I revise one scene at a time. I can focus on one scene. I can re-write one scene. I can eat that one carrot comfortably.
I still have a lot of paper in my "Revision" pile, but I feel accomplishment as I put a scene on the "Finished" pile. It might take me all summer, but I'm going to eat that garden, one bite at a time!
