In his 36 years as the men’s head basketball coach at Duke, Mike Krzyzewski has delivered countless motivational speeches to his players.

On a cloudless, cool May Sunday morning, Coach K was again exhorting Duke students reminding them that attitude, belief, preparation and execution are the keys to being a part of a successful team except this time his words were directed at Duke’s Class of 2016 during the university’s 164th commencement ceremonies.

“There’s nothing more important than attitude, and it’s your choice,” he said.
