The escalating scale of writing revisions:
1. Tiny change.
2. Minor change.
3. Polishing.
4. Tweak.
5. Uncomfortable change but you know it’s right.
6. That thing you ignored hoping no one would notice.
7. Deleting a character.
8. Amalgamating two characters without creating a hideous chimaera.
9. Extensive structural change.
10. Extensive structural change that could affect the very nature of space and time.
11. Turning your story into a canoe instead.
