Use chapter divisions to give the book structure. Chapters are useful because they allow you to move on from discussing certain life periods or events. There's a reason we have the expression that we've "closed a chapter" or "opened a new chapter" in life, and it's even more applicable when discussing an autobiography. Chapter breaks allow you to skip forward 10 years, go back in time, or start describing a new theme without jarring the reader too much.
The theme of your life is to be defined before the story is written. Your goal – and your ultimate achievement of that goal – can be the theme. You should also remember to include something that takes the focus from the past and present, and puts it on the future. A particular event that had a huge impact on your life can be your theme. Find and mark that one day and or one event that twisted your life out of shape and made you think about your future. In general, the end or beginning of somebody’s life has a tremendous impact on many people’s lives. It is around this theme that the story should be woven like rich tapestry of many colors and flavors.
I have lead a very full and sometimes complicated life. I have worked in many different vocations and participated in most all of the arts. I have been ask probably 100s of times why I don’t write a book about my life and or experiences. I realize that aspects of my life are things that should maybe written down for prosperity, but when I begin to think about what to write about, or what area to write about, I am bewildered. To fully write my life would take me volumes of words. I can remember from the age of two until now and yesterday I turned 76. At times I think of things that I think are important, but then other times I think of dozens of things are important. Many of my learned friends call “The Renaissance Man”. I am at a loss.
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.
