According to the fascinating field of “narrative psychology,” the stories we tell about ourselves are the key to our well-being. If you’ve interpreted the events of your life to mean that you’re unlucky or unwise, it’s hard to look optimistically at the future. Conversely, if you acknowledge that you’ve made mistakes and faced difficulties but seek (or have already glimpsed) redemption, you’ll feel a much greater sense of agency over your life.
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.
