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.
The theme of your life is to be defined before the story is written. Your goal – and your ultimate achievement of that goal – can be the theme. You should also remember to include something that takes the focus from the past and present, and puts it on the future. A particular event that had a huge impact on your life can be your theme. Find and mark that one day and or one event that twisted your life out of shape and made you think about your future. In general, the end or beginning of somebody’s life has a tremendous impact on many people’s lives. It is around this theme that the story should be woven like rich tapestry of many colors and flavors.
Incorporate dialogue into your autobiography to make it more personal, recommends history professor Robert Gerlich at Loyola University in New Orleans. Consider including humor when it's appropriate. For example, if you're writing about how you got lost at Disneyland when you were 10 years old and how the experience helped you learn to face obstacles, problem solve and overcome your fears, you might write, "The attendant at Splash Mountain said, 'Are you OK? Did you get separated from your family?' I quickly replied with as much bravado as I could muster, 'Nah, I'm fine. My eyes are just wet from the ride.' I didn't want her to know I was crying."
