The most powerful aspect of applying the techniques of fiction writing to your memoir is that is allows you to do more than simply create a replica of your life. Rather, your memoir becomes a journey into some aspect of your life that is calling to be explored, revisited, and ultimately resolved. To my mind, resolution and healing are the most powerful aspects of memoir writing.
Through writing your memoir, you are invited to explore the past, not record it.
Memoir writing sets your present-day awareness onto past experiences that were confusing, challenging, painful, exciting, beautiful, wretched, or moving.
Writing a memoir gives you the opportunity for a do-over where you become the hero or heroine of your own journey. By this I mean rewriting some incident in your life in which you weren't old enough, safe enough, strong enough, or wise enough to experience in earlier times. I can tell you from personal experience, that approaching memoir from this perspective is not lying; it makes the journey an adventure that has the potential to heal the past! Point of view is the first step toward doing this.
Who is your point of view character? YOU! Not the conscious you trying to remember and recreate, but the adventurous, wise you who has knowings that transcend memory. You begin by letting go of what your perceive as "truth" in order to experience the world through this character who is more than you think you are!
Using The Photograph At The Top Of The Page For Your Scene: Use the above photo as a jumping off for a moment in your life that wants to be explored. You probably have not have been in the exact setting, but you have been in what seems to be a defining moment in your relationship. What is the memory? Is your relationship breaking up? Have you just had an argument? Has a secret between you been uncovered? Has some upsetting event happened? Did one of you receive bad news?
Remember, a prompt is only a jumping off point used to bring up something from your unconscious. Do not be slavish to the picture. See where it takes you. Then let the You, the character who is You, have free rein. What is the "character You" thinking, feeling, doing, saying? You may be surprised!
