I usually start writing a novel that I then abandon. When I say abandon, I don't think any writer ever abandons anything that they regard as even a half-good sentence. So you recycle. I mean, I can hang on to a sentence for several years and then put it into a book that's completely different from the one it started in.
What's the fun in approaching something closed-minded? I'm very specific; if dialogue is too on-the-nose, or there's a lot of telling and not showing, I'll talk to my manager and let them know the problems I have with it. But, I always go in with fresh eyes. The first pass just needs to be about figuring out little things here and there.
