We should make ourselves stop trying to explain our own difficulties. Our first impulse is to try to account for them, figure out why what has happened did happen. Sometimes such an effort is beneficial: more often it is distinctly harmful. It leads to introspection, self-pity, and vain regret; and almost invariably it creates within us a dangerous mood of confusion and despair. Many of life’s hard situations cannot be explained. They can only be endured, mastered, ad gradually forgotten. Once we learn this truth, once we resolve to use all our energies managing life rather than trying to explain life, we take the first and most obvious step toward significant accomplishment.
