" We might pity those who are broken or incapacitated by life’s setbacks. Theirs cannot be a happy existence. We might also sympathize with those who respond to setbacks with frustration and anger. It is such a common response that we might have concluded that it is, for us humans, the default response. Look around us, though, and we can find individuals who quickly bounce back from a setback—or better still, who don’t need to bounce, since they don’t get upset to begin with. Such individuals come off looking strong and even heroic. "
