““We long for experiences “of profound connection with others,” he writes, “of deep understanding of natural phenomena, of love, of being profoundly moved by music or tragedy, or doing something new and innovative.” Just as important, we long for esteem and pride, “a self that happiness is a fitting response to.” Implicit in Nozick’s experiment is the idea that happiness should be a by-product, not a goal. Many of the ancient Greeks believed the same. To Aristotle, eudaimonia (roughly translated as “flourishing”) meant doing something productive. Happiness could only be achieved through exploiting our strengths and our potential. To be happy, one must do, not just feel.””
