|Don't let this be the story of your essay!|
Don't wait to get started. Take the trip through the text that we took today and start trying to form your thesis out of it. Outline, bubble graph, t-chart, mind map -- whatever -- just get going. Don't start writing on Thursday night or in the lab Friday; that's about peer review and getting help. Since neither I nor your classmates can steer parked cars, you need to have a draft of something to critique.
The turnaround on this paper is fairly quick. Don't dawdle.
