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.
Why it helps: There’s no need to do the actual examination and investigation now. Instead, just focus on identifying what it is you might delve into someday—in a memoir or in the pages of a journal or just in your mind. What truth is important for you to get at? You have a structure (your three sentences), you have a crucial event (that may have caused or contributed to that life story) and now you have a purpose—a reason for writing that will let you learn, enjoy and even be surprised by the story you’ve been waiting to tell yourself and—maybe, just maybe, the world, as well.
Were you satisfied with the ending of the memoir? Why or why not? Unlike an autobiography, a memoir does not need to have a linear beginning, middle, and end. Most memoirs end without any firm conclusions or end of life moments. Instead, memoirs may end with thoughts on a running theme throughout the book, or with reflections on the pivotal event or moment in the writer’s life.
Identify your narrator’s desire line. In your memoir, your narrator is you. You will use the first person, “I”, to lead the reader through your story. But it’s important to focus your memoir on specific need or desire. Your want will drive the food forward and make your story worth reading. Think about your desire line, or what motivates your narrator to tell her story. Your narrator will then struggle to achieve her desire line through telling her story and reaching a realization about a pivotal moment in her story.[3]
For example, if you grew up on a farm, you know the difference between the smell of hay and wheat, and certainly that of pig manure and cow manure—because you had to shovel one or all of these at some point. City people probably don’t even know there is a difference. Describing the subtle differences of each and comparing the scents to other scents can help the reader imagine the situation more clearly.

The childhood story. Whether your childhood was happy or traumatic, you should include a few anecdotes that give a picture of who you were and what you experienced at the time. You can tell the story of your childhood by breaking it down into smaller anecdotes that illustrate your personality - your parents' reaction when you brought home a stray dog, the time you climbed out of the window at school and ran away for 3 days, your friendly relationship with a homeless person living in the woods . . . get creative.
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.
