An interesting story about the positive effects of 'story editing', also known as narrative therapy. In this podcast NPR speaks with Psychologist Tim Wilson of the University of Virginia who "has been studying how small changes in a person's own stories and memories can help with emotional health. He calls the process "story editing." And he says small tweaks in the interpretation of life events can reap huge benefits."
