Your life story, or autobiography, should contain the basic framework that any essay should have, with four basic elements. Begin with an introduction that includes a thesis statement, followed by a body containing at least several paragraphs, if not several chapters. To complete the autobiography, you'll need a strong conclusion, all the while crafting an interesting narrative with a theme.
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.
Use chapter divisions to give the book structure. Chapters are useful because they allow you to move on from discussing certain life periods or events. There's a reason we have the expression that we've "closed a chapter" or "opened a new chapter" in life, and it's even more applicable when discussing an autobiography. Chapter breaks allow you to skip forward 10 years, go back in time, or start describing a new theme without jarring the reader too much.
You may wonder how to start an autobiography introduction. The answer is simple: the same way you start other essays’ introductions. The main purpose of the introductory paragraph is to grab the reader’s attention and present the idea and theme of your writing. Don’t make the first paragraph too long: between one and three sentences are enough to compose a regular introduction. Try to provide readers with a general portrait of yourself, so they will know more about the main “hero.” Mention your age, significant personal qualities, and principles of worldview. You can also add some details about your appearance in order to make your story more vivid.
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.
