Marcus offers a practical technique for improving mood and perspective by focusing on the virtues of people around us. Instead of dwelling on others' flaws or our own problems, we can lift our spirits by genuinely appreciating the good qualities in family, friends, colleagues, and even strangers. This practice serves multiple purposes: it counters our natural tendency toward criticism and complaint, it strengthens our relationships by fostering genuine appreciation, and it reminds us that goodness exists everywhere if we choose to notice it. The act of looking for virtue in others also trains us to recognize and cultivate virtue in ourselves.
