These are great tips! Especially about writing what comes to you, not the story you originally set out to write. Sometimes we’re smarter than we even know and something important is trying to come out! I also recommend checking out StoryShelter – it has lots of question prompts to get you writing about your life. See what questions get your attention and maybe do a free write around them to get the juices flowing!
Take steps to self-publish your book. Even if you don't want to worry about trying to sell your book to the public, you might want to have it designed and printed to keep for yourself and give to your family members and other people featured in the book. Research companies that offer book designing, printing, and shipping services, and decide how many copies you'd like to order. Many companies offering these services produce books that look just as professional as those printed by traditional publishing houses.
Weave in themes. Use the major themes of your life as a way to tie stories together, connecting your past and your present. Aside from the central conflict, what themes have followed you throughout your life? A fondness for certain holidays, your fascination with a certain place that you visited over and over, a certain type of guy you've always fallen for, a rich spiritual life you fall back on again and again. Bring up the themes every so often to help form a cohesive picture of your life.
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."
