In positive psychology, zest (or enthusiasm) is among the discrete strengths people possess. Having zest means treating life as an adventure and feeling motivated in challenging situations. People with zest display enthusiasm, excitement, and energy as they tackle life's tasks.[1]: 241 [2] Zest is a component of the virtue of courage in some positive psychology paradigms.
