This is Ann Patchett in the afterward to Lucy Grealy’s Autobiography of a Face.

In the right hands, a memoir is the flecks of gold panned out of a great, muddy river. A memoir is those flecks melted down into a shapable liquid that can then be molded and hammered into a single bright band to be worn on a finger, something you could point to and say, “This? Oh, this is my life.” Everyone has a muddy river, but very few have the vision, patience, and talent to turn it into something so beautiful. This is why the writer matters, so that we can not only learn from her experience but find a way to shape our own. I’m not talking about shaping every life into a work of art. I’m talking about making our life into something we can understand, a portable object that has the weight and power of an entire terrain.
