“resilience—“good outcomes in spite of serious threats to adaptation or development.” Resilience isn’t simply something one is born with; it grows out of an interaction between factors that promote it (like hyperthymic personality) and harmful life events—producing a good outcome in the end. In psychology research, two lines of evidence support this notion. First, when people experience harmful events, some are injured psychologically, but others are not. Second, sometimes people even get stronger after such events, a “steeling” effect that protects them against future stresses. Resilience is the mind’s vaccine.”
