In addressing graduates over the weekend at George Washington University, Apple CEO Tim Cook told students to follow in the footsteps of his predecessor Steve Jobs.

“His vision for Apple was a company that turned powerful technology into tools that were easy to use, tools that would help people to realize their dreams and change the world for the better,” Cook said.

“I had studied to be an engineer and earned an MBA. I was trained to be pragmatic, a problem-solver. Now, I found myself sitting before and listening to this very animated 40-something guy with visions of changing the world. It was not what I had expected.

“At Apple, we believe the work should be more than just about improving your own self. It’s about improving the lives of others as well.”

Cook ended his address by taking a photo of the graduating class with his iPhone.

Sunday’s speech was the first commencement address delivered by an Apple CEO since Jobs spoke at Stanford University’s graduation in 2005.
