"Exuberance is an abounding, ebullient, effervescent emotion. It is kinetic and unrestrained, joyful, irrepressible. It is not happiness, although they share a border. It is instead, at its core, a more restless, billowing state. Certainly it is no lulling sense of contentment: exuberance leaps, bubbles, and overflows, propels its energy through troop and tribe. It spreads upward and outward, like pollen toted by dancing bees, and in this carrying ideas are moved and actions taken."
