Let’s do an exercise.
Consider your current WIP (Work In Progress). Then, ask yourself two questions: (1) Is it complete? (2) What would make it complete?
Now that you have answered those questions, consider this one: What could I do to make this work better? Once you answer this question, now you can go forward. This means you are prepared to look at your work, seeing it as an artist and a critical eye. These things are amazing because it allows you to clear your mind enough to focus on what you desire to write.
The rewrite is your space as a writer to do what Neil Gaiman says: “to look like you knew exactly what you were doing all along.”
