As is present in the biography of a person, your place and time of birth, your parents’ views, an overview of your personality, your likes and dislikes, and important events that shaped your life should always be included in your autobiography. This will give a mental picture of your life to the readers as a sort of backdrop to the main part of the story.

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.”
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.
We told you how to start. When you get through that point, it will be easier to continue. You will follow the plan and you’ll keep developing it. At one moment, you may even notice that the words are pouring themselves out. You’re finally expressing the things you’ve been carrying inside for so long. That may be a torturing process, but it’s also liberating in a strange way.
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.
