When self-published author Ezekel Alan was asked to name the single best thing he’d ever done to help him achieve success, he said, “I wrote the novel the way I wanted.”
While you’re in the creative mode, don’t allow the judge (the logical side) to interfere. The judge will be worried about things like market trends, publisher picks and what agents are taking on right now. Those things can short-circuit the creative flow. Just be with the work until the draft is finished.
Then, once you’ve made the work the best it can be, you can think about those other issues. Logical considerations are important, of course, but write what you want. Adapt your pitch to present the work in the best possible way after it has been written.
