It is my observation that we get stuck in revision when we limit our thinking to good or bad. Those adjectives are judgmental, flat, and as oppositional as a tired two year old.
Why not try shades of BETTER?
Start where you are and strive to make the work BETTER using whatever criteria needs applying (e.g., better for my audience readability, better for the current market need, better for rhythm/cadence/lyricism, etc.). Of course, this means we must first identify the end goal, but that's very doable.
I challenge you to ditch the limitations of "good" or "bad" as they apply to your work.
Good? Bad? Blech. Better is...BETTER.
