As you get one, write it down at the end. Then, when you're done, believe you are not yet done. Go back and read through what you've written, to let that spark new ideas in you. Just continue writing, re-reading, getting new ideas, and writing. T hen, maybe it's time.
Creative time is over.
Let your left-brain do what does so superbly. Let it organize your creativity into a cohesive essay of 3,000 words, fully three days before your deadline. A ll of this is only magic, mirrors, and pixie dust, unless you can believe that it works. Logically, it can never work unless you believe that it works, so logically, there's no evidence that it can work. So, logically, it can't work.
