Obama to grads: Best is yet to come
"I come here not to dispute the suggestion that I haven't achieved enough in my life," Obama told tens of thousands of students. "I come to confirm that one's title, even a title like president of the United States, says very little about how well one's life has been led -- and that no matter how much you've done, or how successful you've been, there's always more to do, always more to learn, and always more to achieve."
