Keep Your Head Up In Failure

Attributed to Seinfeld in interviews on the psychology of success. The advice inverts the conventional wisdom: instead of projecting confidence when things go wrong and celebrating openly when they go right, Seinfeld argues for emotional restraint in exactly the opposite direction — humility in success prevents complacency, and composure in failure prevents despair. The line reflects the same stoic discipline he describes applying to his daily comedy-writing routine.
