Write a rough first draft. You may feel pressure to write and rewrite every sentence you put down. But part of writing a memoir is writing an honest account of a pivotal event, in your own words and with your own style. Avoid putting on a “writer” voice. Instead, don’t be afraid to write like you speak or talk. Include slang and any regional vernacular. Make your story sound like it is coming directly from you.[12]

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.

Why it helps: Sometimes we avoid the most obvious—and complicated—events that have happened to us, events that inform our whole life story. Let’s say your three-sentence exercise was Loving mom who worked all the time, no dad. Never really got over lonely childhood. Maybe you could try, “I was just a kid but...” or “I tried my best but...” Was there something else that happened that prevented you from getting over your lonely childhood? Did it happen when you were a child—or later? Did it involve parents? You don’t have to know the answers to these questions. Let the pre-written prompts guide you. “Don’t think and write,” says Temes. “Just write.”
This is an extremely emotional and intimate type of writing. You share a personal experience with your readers in a detailed manner. Your audience should have an opportunity to see the event or person that you’ve written about through your eyes and understand your feelings. Any personal essay has two main aspects: the description of a particular situation and how it has influenced your worldview and life. Generally, the personal essay is the shortest form of autobiographical writing, along with the essay for college.
Now, it’s time to think on how to conclude an autobiography. Your conclusion has to be strong and impressive. Mention what lessons you’ve learned and what changes in your life you’ve witnessed thanks to the described episode of your life. Even if this event has had negative consequences, you shouldn’t hide anything. Bad experiences are also useful for personal development. As Theodore Roosevelt once said: “The only man who never makes a mistake is the man who never does anything.”
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.
