Not only does writing about your life story change you, it can change others as well. Your history can have a powerful effect on other people’s lives! Especially if you’ve learned, grown and changed through the years. And I suspect you have. You wouldn’t be searching for information on how to write about your life story if nothing every happened to you 🙂
It may help to identify the reading level of the ideal reader of your book. You can determine the reading level based on the grade level of your ideal reader. If you account for ESL readers, you should aim for a grade 6 or 7 reading level. If you are writing for a higher education audience, you may write at a grade 8 or 9 level. You can use the Hemingway app to determine the reading level of your draft, or other online reading level tools.
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.
