Capture the spirit of the times. How was your story shaped by the moment in history in which it took place? What wars influenced your politics? What cultural events inspired you? Be sure to include a few important dates so readers can understand the sequencing of the events you are describing. Discussing what happened in the world at large during your lifetime is a good way to make your story more relevant and interesting to those reading it.
"I was 12 years old when my mother passed away. By the time I was 15, I had become an expert in dodging bill collectors, recycling hand-me-down jeans, and stretching a single meal’s worth of ground beef into two family dinners. Although I was a child when I lost my mother, I was never able to mourn or to let myself become too absorbed in thoughts of personal loss. The fortitude I developed at a young age was the driving force that would see me through many other challenges."
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.
Identify your audience. To create an effective bio you need to determine who will be reading your bio and what impression you want them to have. The purpose of your bio will help identify the audience. For a job application the audience will be employers, for a speaking engagement the audience will be comprised of people interested in the topic you are speaking on.
