"America is an unlikely place - a country built on defiance of the odds; on a belief in the impossible. And I remind you of this because as you set out to live your own stories of success and achievement, it's now your turn to help keep it this way. It's your turn to keep this daringly radical but unfailingly simple notion of America alive - that no matter where you're born or how much your parents have; no matter what you look like or what you believe in, you can still rise to become whatever you want; still go on to achieve great things; still pursue the happiness you hope for. Today, this dream sounds common - perhaps even cliche - yet for most of human history it's been anything but. As a servant of Rome, a peasant in China, or a subject of King George, there were very few unlikely futures. No matter how hard you worked or struggled for something better, you knew you'd spend your life forced to build somebody else's empire; to sacrifice for someone else's cause. But as the centuries passed, the people of the world grew restless. They were tired of tyranny and weary of their lot in life. And as they saw merchants start to sail across oceans and explorers set off in search of new worlds, they followed. It was right here, in the waters around us, where the American experiment began. As the earliest settlers arrived on the shores of Boston and Salem and Plymouth, they dreamed of building a City upon a Hill. And the world watched, waiting to see if this improbable idea called America would succeed. For over two hundred years, it has. Not because our dream has progressed perfectly. It hasn't. It has been scarred by our treatment of native peoples, betrayed by slavery, clouded by the subjugation of women, wounded by racism, shaken by war and depression. Yet, the true test of our union is not whether it's perfect, but whether we work to perfect it. Whether we recognize our failings, identify our shortcomings, and then rise to meet the challenges of our time."
