What to write: Choose one or more of the sentences below and write a page or two that begins with that particular sentence. Don’t worry about bringing up material that you are afraid might be too painful to explore, says Temes. “Please don’t bother with grammar or spelling or punctuation issues. “Just write for yourself and for your clarity of mind.”
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.[2]
It was only when Sophie’s husband accused her of giving birth to another man’s baby that she went for paternity tests and discovered that her husband was right (sort of). The baby, then aged 10, wasn’t his, but she wasn’t Sophie’s either. She belonged to another set of parents, who had been raising Sophie’s biological daughter in a town several miles away.
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.
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.

The idea is not to delude yourself that bad things are actually good. It is, instead, to find meaning in the progression from one event to the next. It is to recognize that everything constantly changes. In your life, you will move from triumph to heartbreak to boredom and back again, sometimes in the space of a single day. What are you to make of so many emotions, so many events?

If your writing is atrocious, or if you just need some help getting your thoughts in order, consider hiring a ghostwriter or a professional personal historian. Celebrities do it all the time. There is also a software that allows you to type your answers into a template on your computer, thus solving the problem of less-than-perfect handwriting. Many people also choose to type directly into an online template.
“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.
Writing autobiography can be nerve-wracking that you can barely start a single letter on. But there are also some instances when the story just keeps on flowing that you won’t even know when to stop. With these two cases, just continue on writing your bio and review all the details you were about to get out from yourself after that. In order to be effective, learn first how to write an autobiography of myself by starting with the basic definition of an autobiography.
These two sets illustrate how you should show the entire action and then show the entire reaction. Don't mix the two together in one paragraph. Write your entire book in this way — action and reaction, one complete set after another. If one part of the set is missing, readers will sense an awkwardness. If you're writing an autobiography, or anything else, action/reaction sequences will make your writing lively and natural. As you expand your ideas, write in action/reaction pairs.
If you graduated from high school despite struggling with dyslexia, you may have a powerful story about perseverance. If you became hugely successful in your career, perhaps your story is rooted in diligence with a dash of luck. While researching this idea in the course of writing the book Writing Your Legacy (WD Books), Richard Campbell and co-author Cheryl Svensson focused on the concept of life themes, developed by the father of gerontology James E. Birren. In the January 2017 Writer’s Digest, Campbell explains why the 10 core legacy themes are an essential piece in puzzling together your memoir. Below, he breaks down each element and poses questions sure to prompt a personal response from writers.
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.
