So now, make a list of everything that seems like a fruitful topic. From the questions and prompts, you should find that you have 3-5 strong topic areas and stories—stuff that got you thinking and feeling, and which produced what Hemingway called the “honest sentences” that comprise good writing. Start with the one that moves you most—that’s your personal statement—but save all the others as fodder for your secondaries, or as backup material in case someone you trust tells you to consider switching topics for some reason. (Tip: the stuff that isn’t always linked to an anecdote or story but is important to you can often be useful for those secondaries.)
There’s no reason to rush your essay. You won’t score extra point with the admissions department for finishing your essay in an hour. Unless you’ve helped write the State of the Union, your admissions essay will likely be the most influential essay you’ve written so far, at least as it relates to your own life. Give yourself at least a week to compose your essay.
