Oprah Winfrey talked about courage, making wise choices and helping others during a commencement address Sunday at Duke University, which gave her an honorary degree. During her 25-minute speech beneath overcast skies, the talk show host told the 4,400 graduates and their guests that “one of the best ways to enhance your own life is to enhance somebody else's” and to “stand proudly in your own shoes while you help others stand in theirs.” “How can I help somebody else move to higher ground? That is success. That's it. That's why we're all alive,” she said. She also emphasized the need to make wise choices daily, saying, “Each of us has to stand in our own shoes. Will you stand in them in humility and compassion and courage? Every day will give you a chance to make that choice.” Duke President Richard H. Brodhead presented Winfrey with an honorary doctor of humane letters degree. Preceding Winfrey was student speaker Robert Paul Jones, a 2002 graduate who returned to Duke to receive his medical degree. He teased her about her celebrity, and pretended to be interrupted by a cell phone call as he began his remarks. “Ms. Winfrey, apparently your limousine is double-parked in front of the chapel,” Jones joked. “Duke Parking wanted me to let you know they won't release your honorary degree until you pay your parking fine.”
