Your readers won’t be interested in reading the whole text of your autobiography if you don’t provide a good impression in the introduction. Convince your audience that your story is unique, original, and is worth their time. If you are going to write about an episode from your childhood, use a feeling of nostalgia to create a tight connection between readers and your own memories. Remember that all people are the same to some extent. We live through similar experiences every day, so you should use these similarities to make your writing attractive for the general public.
"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."
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."
