Analyzing, talking through, and attempting to change thought patterns isn't just a clinical technique for serious problems. In my experience, the smaller the problem and the healthier the person, the more quickly and dramatically it seems to work. Other than people who have been in therapy or who have grappled with mental health issues on their own, I rarely see people using it, with one exception: I see the parents I know using it with their children all the time to help them deal with everyday emotional difficulties such as anger management. A decade from now, there might be a generation of adults who consider it common sense and have no idea it originated in the treatment of mental illness.
