It’s possible that writing your life story could be therapeutic, offering closure on some not so bright spots of your personal history along with emotional and psychological healing. Maybe your life was just a circus act from the beginning and is funny. If writing your life story touches you while you are writing it, think about all the people you can touch when they read it.
Take a step back to reflect. You're chronicling your life lessons, but what have you learned from them? Relay your intentions, desires, feelings of loss, feelings of joy, the wisdom you've gained, and other inner thoughts from time to time throughout the book. Taking a step back from the action of the story to reflect on what it all means is a good way to add depth to your autobiography.
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.
While you might not remember every detail about a certain event, I guarantee someone who was there does remember. Asking family and friends for ideas or details of a certain situation can give you a completely different perspective of the event or time in your life. That perspective might prove to be invaluable in your writing. Be prepared; once you get a group of family and friends together to reminisce, you will be shocked at how quickly the ideas come and how one idea can spark another and another and another.
Culture includes the customs of your family, the holidays you preferred, celebrations and rituals you practiced, the food you ate and the clothes you wore. Include special glimpses into things like the most precious gift you got or popular foods served during special celebrations. These details will be lapped up by a hungry audience that wants to know more about a culture that is different from their own.
Train yourself to use concrete details rather than abstract concepts. Take another leisurely look at what you've written. Highlight abstract phrases such as "I was afraid," or "we had a pleasant time." Replace these abstract words or phrases with something concrete, such as "my hands shook and my mouth felt stuffed with cotton" or "We drank Chardonnay on the Chatterley's sailboat, and as the sun set Rachel and I walked hand in hand along the boardwalk." Was it "a hot day," or was "the asphalt so hot that your flip flops stuck to the tar"? You might go back to the professional autobiographies you're reading and type out a few passages from the books for practice. If you're watching for it, doing so will focus your attention on the concrete. Most ordinary readers won't think about whether or not you've used abstract or concrete terms. They will know whether the writing is boring or interesting. Writing an autobiography with concrete specificity will only improve it.
