Every successful person has experienced countless temporary setbacks, obstacles, and even outright defeats in his or her life. But it has been the ability to respond positively and constructively to these defeats and to bounce back that ultimately has assured success. This quality of bouncing rather than breaking will determine your success as well. Dr. Abraham Zaleznik of the Harvard Business School did a study some years ago on the role that disappointment plays in life. Many people had researched and written on motivation and its relationship to success. But Zaleznik was the first person who looked at the other side of the coin.
