"We don't seek the painful experiences that hew our identities, but we seek our identities in the wake of painful experiences. We cannot bear a pointless torment, but we can endure great pain if we believe that it's purposeful. Ease makes less of an impression on us than struggle. We could have been ourselves without our delights, but not without the misfortunes that drive our search for meaning. 'Therefore, I take pleasure in infirmities,' St. Paul wrote in Second Corinthians, 'for when I am weak, then I am strong.'"
