As promised, read this about the history of the essay. This relates to my comments about essay writing, taking an idea for a walk, and exams. The same model popped up as we listed all that you needed to do to complete the next tasks. Instead of building the list we all slipped into problem solving. You can’t solve problems if you have not yet made a list of all things you need to do to do something. Get the list first, then cross off what you know how to do. Then triage what is most important, next.
