The mess in your draft is not a verdict on your ability. It’s a stage and there’s an order for working through it that keeps you from wasting a year on the wrong end of the problem.

When you’re ready to make the passes
The episode gives you the order. The First Aid Kit for Revision gives you the working tools; the questions to ask at structure, at emotional arc, at scene integrity, and a way to hold your answers while you go.
It won’t tidy your draft for you. It will stop you standing in front of ninety pages with no idea where to start.
