What's your central conflict? What's the biggest obstacle life presented that took years to overcome or come to terms with? Maybe it's an illness you were diagnosed with at an early age, a relationship wrought with turmoil, a series of career setbacks, a goal you worked for decades to achieve, or any other number of things. Look to your favorite books and movies for more examples of conflicts.
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.
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.
If the purpose of your autobiography is to pass on your story to your heirs, consider including memorabilia (e.g. pictures, heirlooms, medals, mementos, letters, etc.) and putting your story in a scrapbook format. Of course, you may not be able to copy the memorabilia that accompanies your autobiography, so you still have to think about what you intend to do with your original work and other items, such as medals or bulky heirlooms.
If the project becomes too much for you at any point, remember that writing an autobiography takes time. Take the pressure off. Relax. This is your autobiography. You can make it as brief or as complete as you like, but don't expect to write it quickly. It may take years. If you want to finish fast, you might try the $14.95 Memorygrabber software I mentioned early. The publisher offers numerous free downloadable pages on their website, so you can decide if that approach will be useful or not.
Writing an autobiography for a high school or a college English class can help you gain a deeper sense of personal identity. An autobiography allows you to tell your story in a way that reveals truths about your values, goals and dreams. Though there's no exact science to writing an autobiography, you should include information about your background, major events that shaped who you are and any core themes in your life. Include specific examples to help readers understand your life history.
