When I'm revising, I have to get the beginning to feel right before I move on. It's not just the pressure of knowing that those first few pages--probably the most edited in the entire manuscript--are important for hooking the reader. At this stage, they're important for me too. They get me fired up to keep going.
Revisions are hard. Sometimes when I get to the middle, problems in my novel seem too big to fix. But I can go back to that "pretty good" beginning, and see the spark of where I'm supposed to be going. Remind myself what I promised the reader, and what my character wants.
