Be revealing. You don't have to be explicit, but it's important to reveal truths about yourself and your life in an autobiography. Don't let the book become a list of your accomplishments, with all the negative material carefully kept under the rug. Present yourself as a whole person, sharing talents and flaws alike, and your readers will be able to identify with you and hopefully root for you as they make their way through your story.
Thanks for an encouraging article! I have often thought about starting to write down my life story but have not yet started. Really, getting where I am now from where I started has been an unlikely and incredible journey. Every time I think about it though I get bogged down in how much there is to write, but if I don’t start I could get hit by a truck and everything I have to say to the few surviving family members I have will die with my brain.
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.
