Why it helps: First off, if you want to write a memoir, this three-sentence description will form the structure of your book. In effect, it’s a supershort story of your life—a beginning, a middle and the now, if you will. Even if you have zero impulse to write another word, however, the exercise can show you how you view yourself, your past and your present, all of which can inform your future. Unless, of course, you change the narrative—a privilege granted to any writer.
Writing an autobiography for a high school or a college English class can help you gain a deeper sense of personal identity. An autobiography allows you to tell your story in a way that reveals truths about your values, goals and dreams. Though there's no exact science to writing an autobiography, you should include information about your background, major events that shaped who you are and any core themes in your life. Include specific examples to help readers understand your life history.
