So are you able to pull those good things out of your story as a whole very soon after you have written said story and then set to work with those good book-bones? Because this has been something I have struggled with a LOT. I can't effectively rewrite my own work until I get a big chunk of distance from it (months). If I try to take it apart and throw out the bad stuff right away I end up making mincemeat of it all.

I feel like a brain surgeon working with chain saws.

I envy your ability to know what needs to stay; your talent for finding the bones.
