I cannot and do not live in the world of discretion, not as a writer, anyway. I would prefer to, I assure you—it would make life easier. But discretion is, unfortunately, not for novelists.
Separate the processes of creation from improving. You can’t write and edit, or sculpt and polish, or make and analyze at the same time. If you do, the editor stops the creator. While you invent, don’t select. While you sketch, don’t inspect. While you write the first draft, don’t reflect. At the start, the creator mind must be unleashed from judgement.
