What to write: Try to summarize your life in two or three sentences. Take your time. Think about your past. “But mostly think about who you are today and how you got that way,” says Roberta Temes, PhD, psychologist and author of How to Write a Memoir in 30 Days. “Maybe you want to focus on a certain relationship, maybe a certain theme...or maybe a feeling that has persisted for years.”
Pull out the best stories. The story of your entire life would start to get pretty long-winded, so you'll have to make some decisions about what anecdotes you're going to include. Begin drafting your manuscript by writing out the main stories that will be woven together to create a picture of your life. There are a few main topics that most autobiographies cover since readers find them fascinating.
Writing an autobiography for a high school or a college English class can help you gain a deeper sense of personal identity. An autobiography allows you to tell your story in a way that reveals truths about your values, goals and dreams. Though there's no exact science to writing an autobiography, you should include information about your background, major events that shaped who you are and any core themes in your life. Include specific examples to help readers understand your life history.
