Arnold Schwarzenegger, then serving as the 38th Governor of California, delivered the commencement address at USC in 2009. His speech was structured around his famous 'Six Rules of Success,' drawn from a life that had taken him from a small Austrian village to becoming the world's greatest bodybuilder, Hollywood's biggest action star, and the leader of the most populous state in America. Rule number one was 'Trust yourself,' and Schwarzenegger illustrated it with his own origin story. As a teenager in Austria, he had told his family he wanted to be a bodybuilding champion and move to America to become a movie star. Everyone — his parents, his friends, his teachers — thought he was crazy. But he had a vision of who he wanted to be, not just what job he wanted to have. The distinction between 'who' and 'what' was crucial: 'what' is a job title, but 'who' is an identity, a way of being in the world.
