Create an outline for your autobiography. This helps determine exactly what you want to include in your book, and it serves as a reminder while you write. Start with some basic information about yourself. Autobiographies usually include factual details about the author's life, and they are presented in chronological order. Include your birth date and birthplace and some important memories from your early childhood. The rest of your outline must include specific events in your life that you want to write about in your autobiography. List each event, and note why you want to include it, what you want to say about it and any insights or ideas you have about that particular time of your life. Don't be afraid to deviate from your outline as you write. It is merely a guideline to get you started.
Engage your audience. If a reader is not interested in a book within the first page or two, she may never finish it. Start your autobiography with something known in the writing world as a "hook." This can be an interesting revelation about you, a dramatic incident in your life or an expression of a powerful emotion. Let the readers believe they are getting to know you right from the start.
Write. If you can, dedicate time each day to your book. You may find that you write best at certain times of the day or in certain settings. Write whenever and wherever you feel most creative. Perhaps you prefer a coffee shop in the morning. Maybe you can write any time or anywhere as long as you have a yellow legal pad on hand. It may seem silly, but small details can make a big difference to a writer. Take advantage of things that inspire you. Don't worry about writing in order. You can arrange your autobiography as you go. Write whatever part of your life is on your mind at the time.
Revise your work. Look back through your autobiography after you have completed it. This gives you a chance to correct any errors you find, rearrange material and add or remove anything you feel is necessary. For an autobiography, check that you have arranged events in chronological order. If an event seems unimportant, you may want to cut it out, or you may find that other events need to be added to truly tell your story. Also, have a trusted friend or writing partner read your autobiography to look for inconsistencies and spelling or grammar errors.
Look for a literary agent to sell your work. Research agents to find out which ones accept autobiographical books. Your agent works as the middleman between you and publishing companies, so it's important to find one that likes the type of work you do. Send a query letter to several agents describing your book. Your letter must also include reasons you believe your book deserves to be published and read. Once you find an agent, she can help you sell your autobiography to a publisher.
