While you might not remember every detail about a certain event, I guarantee someone who was there does remember. Asking family and friends for ideas or details of a certain situation can give you a completely different perspective of the event or time in your life. That perspective might prove to be invaluable in your writing. Be prepared; once you get a group of family and friends together to reminisce, you will be shocked at how quickly the ideas come and how one idea can spark another and another and another.
Why it helps: First off, if you want to write a memoir, this three-sentence description will form the structure of your book. In effect, it’s a supershort story of your life—a beginning, a middle and the now, if you will. Even if you have zero impulse to write another word, however, the exercise can show you how you view yourself, your past and your present, all of which can inform your future. Unless, of course, you change the narrative—a privilege granted to any writer.
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.
