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.
Identify your audience. To create an effective bio you need to determine who will be reading your bio and what impression you want them to have. The purpose of your bio will help identify the audience. For a job application the audience will be employers, for a speaking engagement the audience will be comprised of people interested in the topic you are speaking on.
People choose to write about their lives for a variety of reasons, including a desire to leave a memoir for their children and future generations, to create a record for themselves so they can be reminded of their youthful adventures when they're old and forgetful, and to offer something of value to the rest of the world. Writing a memoir is a very personal experience, but if you're willing to share your life story, it can be incredibly rewarding.
“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.
Pull out the best stories. The story of your entire life would start to get pretty long-winded, so you'll have to make some decisions about what anecdotes you're going to include. Begin drafting your manuscript by writing out the main stories that will be woven together to create a picture of your life. There are a few main topics that most autobiographies cover since readers find them fascinating.
"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."
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.
Limit it to 15 minutes, no more – at least at first. Fifteen minutes, three times a week, always at the same time and always in the same place. Stay there for all 15 minutes even if you can’t think of anything to write. This will set up a rhythm, in the same way we get hungry at mealtimes whether or not we’re really hungry. This isn’t just about finding time to write your life story.
The childhood story. Whether your childhood was happy or traumatic, you should include a few anecdotes that give a picture of who you were and what you experienced at the time. You can tell the story of your childhood by breaking it down into smaller anecdotes that illustrate your personality - your parents' reaction when you brought home a stray dog, the time you climbed out of the window at school and ran away for 3 days, your friendly relationship with a homeless person living in the woods . . . get creative.
