This is one of my favorite anecdotes: Last year, the University of Phoenix enlisted renowned Harvard Business School Professor Clayton Christensen to record a lecture. The university reserved a harbor-view room for Christensen and populated it with young people, so that the camera operators could record their reactions.
Before he began to speak, Christensen noticed that the audience appeared unusually engaged and attractive.
“What school do you guys go to?” he asked.
“We’re not students,” a young man told him. “We’re models.”
