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.
After considering these factors, the next step is writing a draft. Start by looking through the best autobiography openings you can find and figure out which you can use as a model. Make sure that you write in the first person since that’s what autobiographies are all about. Never switch back to second-person or third-person and be consistent in using the first person point of view throughout the entire content.

Conclude the autobiography with an experience gained, a lesson learned and a resolution you decided to take after that. Explain to the reader how that resolution set the tone for whatever you achieved in your life from that point forward. This classic format uses the “hero” theme that is endearing to most people. Everyone loves an underdog who was given lemons and ended up making lemonade!
Remember every significant event, unusual experience, or important person in your life. That might take a considerable amount of time, as we think that your life has been interesting enough, and you have many worthy moments. If you want to write about your childhood, you’d better apply to the “experts” – your parents. Perhaps you did something outstanding and awesome when you were a child.
Create an outline or a graphic organizer of the major topics and ideas you want to cover. For example, you might make a time-order chart -- a chart with event blocks to organize events chronologically. Or, you might draw a cluster web -- a diagram with connected circles -- to divide your autobiography into sections, such as one for relevant background information, one for life-changing events, one for special memories and one for goals and dreams. Focus on reasons why specific events, situations and circumstances were important to you and how they made you feel.
