Rewriting is like scrubbing the basement floor with a toothbrush.
Did I really say that I like revising? I am still working on In Her Eyes, and the revisions have been incredibly difficult. I talked about it with a coworker yesterday, and she gave me some good ideas to heighten the conflict. In my first draft, my hero and heroine move from distrust to trust very quickly, so now I'm going back and (hopefully) making the transition less abrupt and more realistic.
I've also got some world building to do. I was writing so fast to meet the NaNoWriMo word count that I simply plowed forward with the story and told myself to worry about the world building later. It's later, so I must spend some time figuring out some of the fine points.
