If you are just writing for your family, that story might be different than if you were writing your story to be read by the general public. Think about whether or not you want to change people’s names. If your life was a harsh one you may not want to include the real names of the people involved. You may also want to consider whether your life story could be written as fiction. There’s an old adage that “real life is better than fiction.” Maybe your true story could be written in fiction form making it more saleable for mass market.
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.
Understand the memoir genre. In a memoir, you are the main character of your own life story. Many memoirists use the facts of their life story to create an engaging tale for the reader. Because you are relying on your own memories as source material for the story, you may end up describing things differently than others might remember it. The key is to write down things as you remember it, in the most honest way possible. Keep in mind memoirs are different from autobiographies in that memoirs should only cover certain key aspects of your life, not your life from birth until the present day.
You should check your autobiographical essay for mistakes in spelling, grammar, verb tense, style, punctuation, word forms, etc. No matter how emotional or exciting your writing is, your readers will stop reading as soon as they notice the first grammatical mistake. An illiterate author cannot win the trust of the audience, so you should take this step very seriously.
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.
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.
Think honestly about your experiences, too. Don't just focus on the best parts of your memories; think about the details within those times. While Christmas morning may be a magical memory, you might also consider the scene around you. Include details like your mother making breakfast, your father spilling his coffee, someone upset over relatives coming into town, and other small details like that. Understanding the full experience of positives and negatives helps you paint a better picture for the reader and lead to a stronger and more interesting narrative. Learn to tie together all the interesting elements of your life story and craft them into an engaging essay.
These memories are also important because they point backwards to what was, and forwards to what was about to happen, with a sense that there was now a new way of seeing these stretches of time. In each memory, moreover, there is likely to be a huge gift – each will reflect a theme, possibly a major theme, which will play out in the rest of the writers’ life.
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.
