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.

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.

Take a step back to reflect. You're chronicling your life lessons, but what have you learned from them? Relay your intentions, desires, feelings of loss, feelings of joy, the wisdom you've gained, and other inner thoughts from time to time throughout the book. Taking a step back from the action of the story to reflect on what it all means is a good way to add depth to your autobiography.
Why it helps: Sometimes we avoid the most obvious—and complicated—events that have happened to us, events that inform our whole life story. Let’s say your three-sentence exercise was Loving mom who worked all the time, no dad. Never really got over lonely childhood. Maybe you could try, “I was just a kid but...” or “I tried my best but...” Was there something else that happened that prevented you from getting over your lonely childhood? Did it happen when you were a child—or later? Did it involve parents? You don’t have to know the answers to these questions. Let the pre-written prompts guide you. “Don’t think and write,” says Temes. “Just write.”

Write out your life timeline. Start writing your autobiography by conducting research on your own life. Creating a timeline of your life is a good way to make sure you include all the most important dates and events, and it gives you a structure to build upon. You can consider this the "brainstorming" phase, so don't hesitate to write down everything you can remember, even if you don't think the memory will make it into the final version of the book.
