If you are not sure that your whole life path is worth attention, then a memoir is your best choice. It is focused on one particular event, relationship, place, or period of your life that has influenced your personality a lot. Don’t be afraid to express your personal feelings and ideas in your memoir, as it shouldn’t be simply a brief list of facts, but the reflection of your inner world.
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.
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.
Why it helps: There’s no need to do the actual examination and investigation now. Instead, just focus on identifying what it is you might delve into someday—in a memoir or in the pages of a journal or just in your mind. What truth is important for you to get at? You have a structure (your three sentences), you have a crucial event (that may have caused or contributed to that life story) and now you have a purpose—a reason for writing that will let you learn, enjoy and even be surprised by the story you’ve been waiting to tell yourself and—maybe, just maybe, the world, as well.
