Don't. Rewriting is an endless cycle. U will do it again. And again. And soon u will lose motivation because instead of pushing the story forward u will constantly be stuck trying to perfect what does not need fixing. It will drown you in stress as it did to me and many other writers. Finish your stories, and leave the motivation of rewriting to new projects.
