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.
Pull out the best stories. The story of your entire life would start to get pretty long-winded, so you'll have to make some decisions about what anecdotes you're going to include. Begin drafting your manuscript by writing out the main stories that will be woven together to create a picture of your life. There are a few main topics that most autobiographies cover since readers find them fascinating.
Everything happens for a reason. Nothing happens by chance or by means of luck. Illness, injury, love, lost moments of true greatness, and sheer stupidity all occur to test the limits of your soul. Without these small tests, whatever they may be, life would be like a smoothly paved, straight, flat road to nowhere. It would be safe and comfortable, but dull and utterly pointless.
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 not have had the most interesting childhood in the world, but everyone has had a few memorable experiences. Highlight the best parts when you can. If you live in a big city, for instance, you should realize that many people who grew up in the country have never ridden a subway, walked to school, ridden in a taxi, or walked to a store a few blocks away.
Conduct basic research. Depending on your story, you may feel you need to do in-depth research on a certain subject, like air force pilots in WWII or life in a refugee camp in Poland. However, resist doing too much research before you start your first draft. You may get overwhelmed by the amount of information you come across during your research and start to forget your personal take on the facts. Remember that your memoir should focus on your memory of the event, rather than be purely factual or completely accurate.
Writing about your life is important because it gives you a chance to reflect. Journaling is one of the main practices that therapists recommend for promoting mental health. It helps people manage anxiety, cope with stress, and deal with depression. When you maintain a journal and you go through your previous entries, you witness your memories without distorting the reality. You see your progress. You remind yourself of the important things you forgot.
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.
