WARNING: No matter who you are, or what your intentions were when you sat down to write, you will not be the same at the end of your memoir. You will be changed by the writing of your own story. And your story, in turn, will be changed as well.
Writing so deeply and personally about who you have been and what has happened to you changes your perspective on so many things. Perhaps the most impactful of these changes is how you view yourself after the awkward and enlightening experience of crafting the character of yourself in an honest way. This forces us to be (hopefully) more honest than we’re used to being with ourselves.
