#6 Revision is a process of refinement
Editing has nothing to do with how good or bad a story is. Editing has to do with how close a work can get to the best that story will allow. A bad story can be written beautifully, e.g. anything Hemmingway ever wrote, and a good story can be written badly, e.g. the Dialogue of H.P Lovecraft. A story’s relative goodness or badness has nothing to do with what needs to be fixed.
I try to explain this as often as I can when tutoring, but I can’t say it enough. Editing only makes what you have better and has nothing to do with it being bad. That said, you can tell when something has not been edited- and we call those works “bad” because the author was lazy, not because the story was terrible.
Try to keep this in mind as you edit. The goal is to remove what isn’t working, and when someone points out errors to you throw away your ego because if it didn’t work for them your book will be in the on sale section of the bookstore. Edit with the doors open, and let in feedback. Don’t let your emotions reign, just say- “wow this is terrible I can do better!” Because you can do better.
A way to remember this is: Polish off the grease before you ride, bucko.
