奥巴马在迈阿密戴德学院2011年毕业典礼上的演讲
Pursue success. Do not falter. When you make it, pull somebody else up. Preserve our dream. Remember your life is richer when people around you have a shot at opportunity as well. Strive to widen that circle of possibility; strive to forge that big, generous, optimistic vision of America that we inherited; strive to carry that dream forward to future generations.
