Sleep on it: separate yourself from your writing by a full night's rest before revising

Get feedback: you don't know your writing expresses anything let alone anything it's meant to if you don't test it on people outside of your head (subtip: learn how to ask for feedback - there's an episode of the podcast Start With This [#3 or #4 iirc] that digs into this)

Try to delete half of what you wrote: half of what you wrote is probably trash, confusing, needlessly ornamental, and/or boring.
