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.
Not necessarily a writer, but still want to record your story somehow? Don’t think that there’s no hope for you. Consider making audio or video recordings. Audio recordings can be especially helpful. You can take audio recordings to a writer/transcriptionist who can then type out your story in a logical order. Working closely with a writer as you verbally record your stories can be an alternative when you feel you are too close to the story.
"Most people don’t think of spiders when they bite into a tomato, but I do. Growing up in southern Ohio, I spent many summer afternoons picking baskets of tomatoes that would be canned or frozen and preserved for cold winter’s dinners. I loved the results of my labors, but I’ll never forget the sight of the enormous, black and white, scary-looking spiders that lived in the plants and created zigzag designs on their webs. In fact, those spiders, with their artistic web creations, inspired my interest in bugs and shaped my career in science."
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.
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.
