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.
Identify your audience. To create an effective bio you need to determine who will be reading your bio and what impression you want them to have. The purpose of your bio will help identify the audience. For a job application the audience will be employers, for a speaking engagement the audience will be comprised of people interested in the topic you are speaking on.
Build tension and suspense. Structure the narrative so that you have a series of stories leading up to the climax of the conflict. If your central conflict is trying to reach the goal of competing in the Olympics for skiing, lead up to it with stories of small successes and plenty of failures. You want your readers to ask, will she make it? Can he do it? What's going to happen next?
The requirements: These are what must be accomplished to achieve the goal. Think of it as a checklist of one or more events. As the requirements are met in the course of the novel, the reader will feel the narrator is getting closer to attaining the goal. Requirements create a sense of anticipation in the reader’s mind, as he looks forward to the narrator’s success.
Your readers won’t be interested in reading the whole text of your autobiography if you don’t provide a good impression in the introduction. Convince your audience that your story is unique, original, and is worth their time. If you are going to write about an episode from your childhood, use a feeling of nostalgia to create a tight connection between readers and your own memories. Remember that all people are the same to some extent. We live through similar experiences every day, so you should use these similarities to make your writing attractive for the general public.
You are not the first person who wants to write about his or her life. Many famous writers, artists, politicians, and businessmen create autobiographies to share their wisdom and experience with a wide audience. Find the autobiography that belongs to the author whose personality inspires you and read it in order to get a basic understanding of autobiographical writing.
Write out your life timeline. Start writing your autobiography by conducting research on your own life. Creating a timeline of your life is a good way to make sure you include all the most important dates and events, and it gives you a structure to build upon. You can consider this the "brainstorming" phase, so don't hesitate to write down everything you can remember, even if you don't think the memory will make it into the final version of the book.
