What to write: Try to summarize your life in two or three sentences. Take your time. Think about your past. “But mostly think about who you are today and how you got that way,” says Roberta Temes, PhD, psychologist and author of How to Write a Memoir in 30 Days. “Maybe you want to focus on a certain relationship, maybe a certain theme...or maybe a feeling that has persisted for years.”
"Today, the plains and low hills of southeastern Ohio make the perfect setting for large cracker box-shaped farmhouses surrounded by miles of corn rows. Many of the farming families in this region descended from the Irish settlers who came rolling in on covered wagons in the 1830s to find work building canals and railways. My ancestors were among those settlers."
The consequence(s): Ask yourself, What disaster will happen if the goal is not achieved? What is my protagonist afraid will happen if she doesn’t achieve the goal or solve the problem? The consequence is the negative situation or event that will result if the goal is not achieved. The combination of goal and consequence creates the main dramatic tension in your plot. It’s what makes the plot meaningful.
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.
Create an outline or a graphic organizer of the major topics and ideas you want to cover. For example, you might make a time-order chart -- a chart with event blocks to organize events chronologically. Or, you might draw a cluster web -- a diagram with connected circles -- to divide your autobiography into sections, such as one for relevant background information, one for life-changing events, one for special memories and one for goals and dreams. Focus on reasons why specific events, situations and circumstances were important to you and how they made you feel.
