One of my favorite writerly things to do is cracking open a chapter the morning after I've announced I've "finished" it and running some good fine-grit editing sandpaper over it, slowly, quietly, thoroughly, until it's a smooth as a vermouth-free martini.
There. Now *that's* a chapter five to be proud of.
@ceoln I think we bring a different brain to editing something that’s already “good enough” some time after it is “done”.
