If you are just writing for your family, that story might be different than if you were writing your story to be read by the general public. Think about whether or not you want to change people’s names. If your life was a harsh one you may not want to include the real names of the people involved. You may also want to consider whether your life story could be written as fiction. There’s an old adage that “real life is better than fiction.” Maybe your true story could be written in fiction form making it more saleable for mass market.
People choose to write about their lives for a variety of reasons, including a desire to leave a memoir for their children and future generations, to create a record for themselves so they can be reminded of their youthful adventures when they're old and forgetful, and to offer something of value to the rest of the world. Writing a memoir is a very personal experience, but if you're willing to share your life story, it can be incredibly rewarding.
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."
