Your Inner Critic mostly wants to be heard. The trick is to let him speak–but not to listen too closely (especially when you’re drafting!)
In my own drafts–both digital and handwritten, I use the following technique: If I’m writing along and suddenly my inner critic points out something, I simply insert a square bracket, write its comment, close the bracket, and proceed with the story.
If I’m doing this on the computer, I turn the comment red so it stands out during editing. That way I can review the comments later (some of them may be on to something, after all) when I’m not in the flow of writing. I get to write, the Critic gets heard, and everybody wins.
It was when I found out I could make mistakes that I knew I was on to something. ~Ornette Coleman
