Identify the main characters. Every good story has interesting characters, friends and foes who help move the plot along. Who are the characters in your life? It's a given that your parents will play a role, along with your spouse and other close family members. Think beyond your immediate family to others who have affected your life and should play a role in your autobiography.
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.
Use simple words and phrases: Think from reader’s point of view. Do not imagine that everybody will know what you know. Readers will be fed up if the story narration demands scrambling for a dictionary each time they come across a big word or surfing the net for new topics that you haven’t described at least in brief. Use only simple words and phrases that everyone can understand, and when introducing a new concept or subject, explain it so they know what you’re talking about.
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.
Create an overarching plot. Now that you know what content you want to include in your autobiography, think about how you want to structure your book. Like any great book, your autobiography needs a great plot. Work with the material you have to craft an interesting story that builds toward a climax and ultimately resolves. Create a narrative arc by organizing and filling out your written memories and anecdotes so that they flow together logically.
Discuss any special circumstances such as obstacles or challenges you've faced, and how you've dealt with them, recommends Xavier University. This is especially important if your autobiography is for a college or scholarship application. For example, you might write about struggles you faced growing up in a multiracial family or how you've learned to live life to the fullest, despite being a diabetic. Your autobiography should be an honest representation of who you are, so avoid embellishments and exaggerations, suggests author and public speaker David Ford. The goal is to help readers understand how events, hardships and experiences have molded you into the person you are today.
