It might be tempting to start your story with "I was born in Dayton, Ohio...," but that is not really where your story begins. It's better to start with an experience. You may wish to start with something like why you were born where you were and how your family's experience led to your birth. If your narrative centers more around a pivotal moment in your life, give the reader a glimpse into that moment. Think about how your favorite movie or novel begins, and look for inspiration from other stories when thinking about how to start your own.
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.
What's your central conflict? What's the biggest obstacle life presented that took years to overcome or come to terms with? Maybe it's an illness you were diagnosed with at an early age, a relationship wrought with turmoil, a series of career setbacks, a goal you worked for decades to achieve, or any other number of things. Look to your favorite books and movies for more examples of conflicts.
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.
As is present in the biography of a person, your place and time of birth, your parents’ views, an overview of your personality, your likes and dislikes, and important events that shaped your life should always be included in your autobiography. This will give a mental picture of your life to the readers as a sort of backdrop to the main part of the story.
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.
Pull out the best stories. The story of your entire life would start to get pretty long-winded, so you'll have to make some decisions about what anecdotes you're going to include. Begin drafting your manuscript by writing out the main stories that will be woven together to create a picture of your life. There are a few main topics that most autobiographies cover since readers find them fascinating.
