Acting with spontaneity might mean bursting into song on the street, or throwing down your rake and jumping in a pile of leaves — in other words, doing something without thinking it through beforehand.

The noun spontaneity is related to a more common word, the adjective spontaneous. The writer Ralph Waldo Emerson said, “Our spontaneous action is always the best. You cannot, with your best deliberation and heed, come so close to any question as your spontaneous glance shall bring you.” He meant that if we learn to trust our instincts instead of weighing the potential consequences of everything we do, we'll make better decisions.
