The success of a good autobiography and any book – comes from the ability of the author to show readers the story from the “outside”, and make the reader feel in your place, “in your shoes.” Everyone does not care about your difficult childhood, or your parents’ divorce, or the fact that in school you were a fat and ugly kid with glasses. But if the difficulties experienced by you will be displayed so that the reader learns some lessons for himself – this would qualify as a good 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.
