Author Daniel Coyle talks with EconTalk's Russ Roberts on the art of flourishing: why it's a natural phenomenon rather than mechanical; how taking life's "yellow doors"--or detours from a straight, expected path--is often the key to a flourishing life; and why true flourishing can only occur in the context of relationships. They also discuss how the basic principles of flourishing have empowered people--from men trapped in a Chilean mine to senior citizens reliving their youth--to achieve remarkable things. Finally, they offer an exercise you can do for recognizing the ways that others have helped us to thrive.
