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.
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.
If the purpose of your autobiography is to pass on your story to your heirs, consider including memorabilia (e.g. pictures, heirlooms, medals, mementos, letters, etc.) and putting your story in a scrapbook format. Of course, you may not be able to copy the memorabilia that accompanies your autobiography, so you still have to think about what you intend to do with your original work and other items, such as medals or bulky heirlooms.
For example, let's say you wrote, "From the age of ten, I knew I would become a concert pianist." What specific event triggered this determination? Can you describe that one event in a paragraph or two, using all the senses available to you—sight, sound, taste, touch, and smell? Using all five senses will help readers imagine the moment as if they were present with you. This vicarious act of reliving events arouses more emotion in readers than simple summary. and if you can master it, you are well on your way to writing an autobiography! Sensory description: The narrow plank felt warm and smooth beneath my bare feet. I ran its length in three strides, arms extended out from my sides for balance. At the end I took a weightless leap into eighteen inches of space. I caught a barely-there flash of metal just before I landed hard, all my weight on my front foot. Then pain like a red-hot poker jammed through my arch, and the gleaming tip of a three-inch nail as it emerged through the top of my foot. Summary: That day I jumped on a board with a nail in it and it went through my foot.
The consequence(s): Ask yourself, What disaster will happen if the goal is not achieved? What is my protagonist afraid will happen if she doesn’t achieve the goal or solve the problem? The consequence is the negative situation or event that will result if the goal is not achieved. The combination of goal and consequence creates the main dramatic tension in your plot. It’s what makes the plot meaningful.
“I was born in 19XX year, I entered school N…” Would you read that if you had a choice? Most likely not, especially if you already have read a dozen biographies which star with the same phrase. Yes, an autobiography is a formal piece of writing. But here, it rather means that you are not allowed to use slang and colloquial language, instead of following a specific pattern of writing.
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.
What's your central conflict? What's the biggest obstacle life presented that took years to overcome or come to terms with? Maybe it's an illness you were diagnosed with at an early age, a relationship wrought with turmoil, a series of career setbacks, a goal you worked for decades to achieve, or any other number of things. Look to your favorite books and movies for more examples of conflicts.
Be revealing. You don't have to be explicit, but it's important to reveal truths about yourself and your life in an autobiography. Don't let the book become a list of your accomplishments, with all the negative material carefully kept under the rug. Present yourself as a whole person, sharing talents and flaws alike, and your readers will be able to identify with you and hopefully root for you as they make their way through your story.
