Pull out the best stories. The story of your entire life would start to get pretty long-winded, so you'll have to make some decisions about what anecdotes you're going to include. Begin drafting your manuscript by writing out the main stories that will be woven together to create a picture of your life. There are a few main topics that most autobiographies cover since readers find them fascinating.
Many people cannot resist the temptation to tell as much as they can, but a longer piece of writing doesn’t always equal a better piece of writing. For whatever reason you are writing the autobiography, think of the person who is going to read it. Imagine you were an admission officer or the judge in the scholarship committee, and you have to choose from hundreds, if not thousands, of autobiographies. At some point you will hate people who prefer to write long admission essays and autobiographies. There’s also a good way to check whether your writing is interesting or not. Give it to one of your most impatient friends, who prefers short articles to books and long stories, and ask for their opinion.
If you think about it, most of us are already sharing our personal stories nowadays. What do you think social media is? We pour out pages and pages with our opinions. We publish photos as testimonials of our daily life. All that can belong to the genre of “creative nonfiction.” Turning a life story into a novel, however, is something else. It has to involve elegance, creativity, and some warmth and humor.
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.
