A stress reduction, pain reduction or mood control method and system, includes having a user: acknowledging a positive activity, completing a math problem in which the user tries to answer the math problem correctly, completing another math problem trying to answer the other math problem incorrectly, and repeating various ones of these steps until the user experiences a positive mood. The process may be followed using a camera or video camera, while analyzing the image(s) for a Duchenne smile, in place of or in addition to measuring an indicator of stress.
