Gratitude is an emotion expressing appreciation for what one has—as opposed to, for example, a consumer-driven emphasis on what one wants. Gratitude is getting a great deal of attention as a facet of positive psychology: Studies show that we can deliberately cultivate gratitude, and can increase our well-being and happiness by doing so. In addition, gratefulness—and especially expression of it to others—is associated with increased energy, optimism, and empathy.
