Write a rough first draft. You may feel pressure to write and rewrite every sentence you put down. But part of writing a memoir is writing an honest account of a pivotal event, in your own words and with your own style. Avoid putting on a “writer” voice. Instead, don’t be afraid to write like you speak or talk. Include slang and any regional vernacular. Make your story sound like it is coming directly from you.
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.
