The document discusses the planning stage of writing an essay. It explains that planning is an important first step that should be done quickly to allow more time for research and writing. The planning stage involves developing a schedule that includes researching references, selecting evidence to support points, and using the evidence to develop a thesis statement and outline. An example schedule is provided that outlines researching for one week, selecting evidence the next, developing a thesis the following week, and then writing and revising over subsequent weeks before a deadline.
