It cannot be overstated that gratitude is an emotion, a complex set of feelings involving appreciation, humility, wonder, and interdependence. Gratitude is, however, more than just an emotion. It is also a disposition that can be chosen and cultivated, an outlook toward life that manifests itself in actions—it is an ethic. By “ethic,” I mean a framework of principles by which we live more fully in the world. This ethic involves developing habits and practices of gratefulness that change us for the better. Gratitude involves not only what we feel, but also what we do.
