The Five-Minute Kindness Rule

Adam Grant's research into why generous people burn out revealed a single filter that separates sustainable givers from depleted ones: cost-benefit asymmetry. The Five-Minute Kindness Rule compresses fifteen chapters of behavioral science into one decision heuristic. If a favor costs you under five minutes but delivers weeks of value to someone else, do it without deliberation. For anything longer, choose deliberately. Drawing on Elizabeth Dunn's spending research and Sonja Lyubomirsky's happiness studies, this principle turns procrastination into kindness's only real enemy.

You'll learn:

- Why the brain's reward circuit sustains rather than cheapens generosity

- How responsibility diffuses in crowds and what breaks the spell

- The thirty-day protocol that shifts identity from doer to giver
