In 2010 world-renowned innovation expert Clayton M. Christensen gave a powerful speech to the Harvard Business School's graduating class. Drawing upon his business research, he offered a series of guidelines for finding meaning and happiness in life. He used examples from his own experiences to explain how high achievers can all too often fall into traps that lead to unhappiness. The speech was memorable not only because it was deeply revealing but also because it came at a time of intense personal reflection: Christensen had just overcome the same type of cancer that had taken his father's life. As Christensen struggled with the disease, the question "How do you measure your life?" became more urgent and poignant, and he began to share his insights more widely with family, friends, and students.
