Revision is opportunity. It is the opportunity to “see your paper again” (re-vision). It is the opportunity to see what you do and what needs work. It is the best opportunity for your writing and your voice to grow.
Even when a draft is completed, the writing process is just beginning. Revisions are your chance to create the paper you want to create.
Higher-level concerns are for revising and editing. These changes will usually be the biggest and most important for communicating your ideas. Without them, the argument may not develop.
Lower-level concerns are for proofreading. These changes focus on readability and sentence-to-sentence flow. Lower-level concerns are good at reminding you that a paper should be focused on the reader.
