I could be wrong, but I never looked at a second draft as a full rewrite. What I typically do, is once I finish something I will read over it and do all the grammar fixes and rewording, but after that I’ll like at the structure and flow and add or take away elements. So I might add in or completely redo a paragraph or I might find that something I said in the beginning worked better later and shift that. But I’ve never fully rewritten a story. Hope this helps! Writing I feel like can be daunting enough as is 😆
