Positive psychology focuses on optimal human functioning and thriving. Martin Seligman founded the field to study happiness and normal lives, not just mental illness. Two approaches to happiness are savoring, consciously attending to pleasure, and flow, fully immersing in an activity. Mihaly Csikszentmihalyi extensively researched flow and defined its characteristics. Work can induce flow more than leisure, paradoxically. Savoring involves mindfully appreciating positive experiences through sharing, memory building, and other techniques to enhance well-being.
