Start by writing the story of your life for yourself first. After you edit and polish it, share it with a few trusted people. Then, after you edit and polish it again, share your life story with a wider swath of people. This will help ensure your memoirs are your best possible work, and that your writing is something you’ll be proud of at the end of your life.
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.
These two sets illustrate how you should show the entire action and then show the entire reaction. Don't mix the two together in one paragraph. Write your entire book in this way — action and reaction, one complete set after another. If one part of the set is missing, readers will sense an awkwardness. If you're writing an autobiography, or anything else, action/reaction sequences will make your writing lively and natural. As you expand your ideas, write in action/reaction pairs.
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.
