Organize what you've written according to cause and effect and action and reaction. Ordering events according to cause and effect is a natural process. Your car broke down, so you called a tow truck. That's cause and effect. You received a promotion, so you bought a house. Action/reaction happens paragraph by paragraph. He said "No," so you said "Why?" That's action/reaction. She set a wet glass on the table, so you placed a coaster under it, and remembered how your mother used to crochet pretty little coasters and starch them. That's action/reaction.

“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.
Many people who have something to tell, have an experience, or have the knowledge and vision “as it should be.” What if you decided to write your own book and it’s not a novel about love and adventures? To become a good writer or to write an interesting book is not an easy task. Unfortunately, this won’t totally depend on hard work, diligence and regular training: you can sit with a laptop, paper, pen or voice recorder at least eight hours every day – and still, you will get something dull and colorless that nobody wants to read. Not always does the desire to write a book match the capabilities and talent. But making effort and progress is still necessary. Anyone who wants to write their first book, should read and write, try different styles and genres, and listen to the world around. The main thing is to throw into trash away all “must” and “deserving / not deserving of attention,” ideas which aspiring authors often suffer from. Here are an autobiography topics list and autobiography examples which can help you.

Create an outline or a graphic organizer of the major topics and ideas you want to cover. For example, you might make a time-order chart -- a chart with event blocks to organize events chronologically. Or, you might draw a cluster web -- a diagram with connected circles -- to divide your autobiography into sections, such as one for relevant background information, one for life-changing events, one for special memories and one for goals and dreams. Focus on reasons why specific events, situations and circumstances were important to you and how they made you feel.
