"After a heated dispute, we each undertook an assignment for the next class: to engage in one pleasurable activity and one philanthropic activity, and write about both. The results were life-changing. The afterglow of the "pleasurable" activity (hanging out with friends, or watching a movie, or eating a hot fudge sundae) paled in comparison with the effects of the kind action. When our philanthropic acts were spontaneous and called upon personal strengths, the whole day went better. One junior told about her nephew phoning for help with his third-grade arithmetic. After an hour of tutoring him, she was astonished to discover that "for the rest of the day, I could listen better, I was mellower, and people liked me much more than usual." The exercise of kindness is a gratification, in contrast to a pleasure. As a gratification, it calls on your strengths to rise to an occasion and meet a challenge. Kindness is not accompanied by a separable stream of positive emotion like joy; rather, it consists in total engagement and in the loss of self-consciousness. Time stops."
