Mike Tyson might have a new career as a philosopher. Indeed, his point about life being comprised of a long series of losses is not only insightful but also motivational. Tyson contends that a person’s drive and stamina to rise above loss is the defining mark of a winner. Martin Luther King, Jr. echoed this sentiment when he argued that “The ultimate measure of a person is not where they stand in moments of comfort and convenience, but where they stand at times of challenge and controversy.” Our long-standing psychometric studies back up this view. Specifically, high performers scored significantly higher on measures of resilience, adaptability, self-directedness, and personal accountability than those with poorer performance appraisals. At no point in our lifetime have these traits been so important.
