Positive Psychology is the scientific study of the strengths that enable individuals and communities to thrive. The field is founded on the belief that people want to lead meaningful and fulfilling lives, to cultivate what is best within them, and to enhance their experiences of love, work, and play. Positive Psychology has three central concerns: positive emotions (positive subjective experience), positive individual traits (the strengths and virtues), and positive institutions (those which surround us and help us to lead our lives in a better way). By understanding positive psychology and applying it into interventions, it promises to improve the quality of life and prevent the pathology that arises when life is barren and meaningless.
