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.
Do you remember any other challenges you had to overcome that relate to each main point in the story? Did you move? Were you ill? Did anyone close to you die? Did any of these people or events affect the choices you made during that stage of your life? Do you remember any amusing or embarrassing incidents related to this success or failure? What high points and low points do you recall? Was a specific holiday or celebration memorable? A specific meal or car ride?
Outline the inciting incident and the ending incident. Often, writers have a difficult time to determining how to start a story. A memoir can be even more challenging as you might feel you have so many details and scenes you could start with or that feel important. One way to start is to identify the inciting incident in your story and the ending incident. You will need to dramatize your inciting incident and your ending incident in your book.
Develop a central theme, main idea or thesis that clearly explains the purpose behind your autobiography. For example, your theme might be about how you overcame obstacles to become a stronger person, or it might explain why a particular passion -- such as mountain climbing or rescuing animals -- is so important to you. Back your theme with details and background information about your life experiences. For example, you might explain that your dad is in the military, so you've had to learn how to adapt quickly to new schools and unfamiliar environments. Or, you might discuss what it was like growing up in a poor, single-parent home, but how your family was always willing to take in injured or stray pets.
