An autobiography is a self-written account of one's own life experiences and history. It can take various forms, such as intimate writings made during life, books, memoirs, or memory books. Reading an autobiography can offer a unique perspective and insight into a person's world and experiences that may be vastly different from our own. The purpose of an autobiography is to tell the true story of one's life in their own words. There are three primary formats of a memory book: biography, autobiography, and memoir. Auto and bio mean "self" and "life" respectively, reflecting the idea of a person narrating their own life story. Autobiographies are often used to highlight events or individuals in a way that can inspire or educate readers.
