Editing?

So, I'm STILL working on THE BET. This book has been a long-slog for me, mostly because I keep editing the plot! Not the overall plot, just the way I want the last half of the book to go. Unfortunately, events shape characters, and every time I change an event to make my plot flow better, I end up learning more about my characters and their motivations. Then I end up rewriting things earlier in the story to make them fit!

ARG. Editing is important, I know, but it drives me crazy....
