While you might not remember every detail about a certain event, I guarantee someone who was there does remember. Asking family and friends for ideas or details of a certain situation can give you a completely different perspective of the event or time in your life. That perspective might prove to be invaluable in your writing. Be prepared; once you get a group of family and friends together to reminisce, you will be shocked at how quickly the ideas come and how one idea can spark another and another and another.
People usually tend to think that writing all this will be monotonous for them and boring for their potential readers, but you will soon find your life to be unique from anyone else’s as you undertake this task. Add in information like interesting snippets from the lives of your ancestors, their achievements and the popularity of your place of birth. This will inspire readers to gather even more information from other sources.
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.

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."
