Start by writing the story of your life for yourself first. After you edit and polish it, share it with a few trusted people. Then, after you edit and polish it again, share your life story with a wider swath of people. This will help ensure your memoirs are your best possible work, and that your writing is something you’ll be proud of at the end of your life.
Yes, you have to be precisely honest and quite revealing and candid to write a successful autobiography. And obviously, you need to describe some hardships of your life to show how you coped with that or how it influenced you. However, we strongly advise you to describe the thing that you feel rather calm about when writing. For example, you are writing about other students picking and making fun of you at high school. If you still feel like wanting to kill them all, it would be better to avoid this topic or mention it slightly. Why so? Because your feelings will leak into the writing and make your reader feel subconsciously uncomfortable.
Identify the main characters. Every good story has interesting characters, friends and foes who help move the plot along. Who are the characters in your life? It's a given that your parents will play a role, along with your spouse and other close family members. Think beyond your immediate family to others who have affected your life and should play a role in your autobiography.
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."
