I had an enormous epiphany about my main character today, while I was running errands (I love it when stuff like that happens), and I find myself on the horns of a dilemma: do I start out fresh, with a clean slate, or try to hammer what I've already got into shape?
I'm not really asking you guys to answer the question for me, I'm just curious what other people do. My manuscript is about 80K words right now -- in other words, it's pretty fleshed out, except for a couple of spots -- so starting a clean re-write is a big decision, but with this new understanding of my protag and the thrust of her experience through the story, I'm probably going to have to 'tweak' a lot of what's already there anyway. If I do re-write, this will be the fourth time I've started from scratch; however, the other three times I had nowhere near this much time/material invested.
So -- is starting a fresh re-write at this point a completely daft idea? Or is it something people do?
