I really enjoyed these from author Karen E Bender at the Story Prize blog. #10 resonated with me the most:
Remember that revision is a process and happens in stages. The first stage, you may be trying to find out what the story is about. Then you may develop scenes, layer characters. Later, you may compress scenes/characters. Then you may work on pacing. A late revision focuses on clarity and language. You may work on any of these issues during the process, but try not to get too focused on honing the language too early, as you may not know what will remain in the story. As one writer I know says, “Writing a story is like building a boat. I don’t want to spend too much time intricately painting a hatch when I don’t know if the boat even has a rudder.”
My writing tip in general: Remember that writing takes up a lot of time.
