As a high school student, Yahoo's famous CEO, Melissa Mayer, attended the National Youth Science Camp. One day, a post-doctoral student from Yale named Zune Nguyen was a guest lecturer. He stunned all the smart kids with puzzles and brainteasers.
The campers couldn’t stop talking about him so one of the counselors pointed out that what made Zune amazing was not what he knows. "It’s how Zune thinks.”
You could put him in a new environment or present him with an entirely new problem and within minutes he would be asking the right questions and making the right observations.
