Also, it’s important to know who you’re writing your life story for. Writing for your family and friends is great! But it requires a different perspective than writing for publication. If you’re interested in getting your life story published by a traditional publishing house, then you’ll need a whole different perspective than if you’re self-publishing your memoirs.
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.
