Shitty First Draft Response

I loved reading Anne Lamott's Shitty First Drafts, from Bird by Bird.  It had a delightful sence of humor to it, especailly the bit about loosing subscribers due to comparing brians to foods. In my freshman english class in high school, my teacher would have us write about anything we could think of on our topic for 5 minutes.  It could go off topic, and even be "this is an utter waste of my time, I hate writing" or "my hand is really starting to hurt."  It didn't matter to her as long as we were writing the whole time.  Then we would go thought, like the author does, and circle anything that we could use, and write a draft from the brainflow.
