Shrink Definition
Broaden-and-build theory holds that positive emotions widen our attention and thinking in the moment, and build lasting resources over time. Where fear narrows us to fight or flee, joy, curiosity, and love open us to explore, connect, and create. Those broadened moments accumulate into skills, bonds, and resilience. Small good feelings compound.
