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.
It might be tempting to start your story with "I was born in Dayton, Ohio...," but that is not really where your story begins. It's better to start with an experience. You may wish to start with something like why you were born where you were and how your family's experience led to your birth. If your narrative centers more around a pivotal moment in your life, give the reader a glimpse into that moment. Think about how your favorite movie or novel begins, and look for inspiration from other stories when thinking about how to start your own.
What to write: Try to summarize your life in two or three sentences. Take your time. Think about your past. “But mostly think about who you are today and how you got that way,” says Roberta Temes, PhD, psychologist and author of How to Write a Memoir in 30 Days. “Maybe you want to focus on a certain relationship, maybe a certain theme...or maybe a feeling that has persisted for years.”
The inciting incident is the pivotal moment in your story, where you realized your desire line. It could be a seemingly small moment, such as a brief fight with your mother, that becomes a major moment or inciting incident in your story. For example, your brief fight with your mother could be the last time you speak to her before she passes away and leaves you letters about her life in Poland. Think of the ah ha moment in your story when you realized what you wanted in your life, or where you realized you were wrong about your assumptions about a specific moment or event.
“I was born in 19XX year, I entered school N…” Would you read that if you had a choice? Most likely not, especially if you already have read a dozen biographies which star with the same phrase. Yes, an autobiography is a formal piece of writing. But here, it rather means that you are not allowed to use slang and colloquial language, instead of following a specific pattern of writing.
Limit it to 15 minutes, no more – at least at first. Fifteen minutes, three times a week, always at the same time and always in the same place. Stay there for all 15 minutes even if you can’t think of anything to write. This will set up a rhythm, in the same way we get hungry at mealtimes whether or not we’re really hungry. This isn’t just about finding time to write your life story.
