Editing is easy to overdo. You open your latest draft to restructure a scene, but as you reread your work to get your bearings, you can’t resist tinkering with a clunky paragraph in the previous chapter. Then you remember a worldbuilding element you need to research so you can use it to set the mood when your protagonist meets her love interest. And soon you’ve spent an hour brainstorming the perfect analogy for his blue eyes.
