My fellowAmericans, you, too, must play your part in our renewal. I challenge a new generation of youngAmericans to a season of service, to act on your idealism, by helping troubled children, keeping company with those in need, reconnecting our torn communities.

In serving we recognize a simple, but powerful, truth: we need each other, and we must care for one another. Today we do more than celebrateAmerica, we rededicate ourselves to the very idea ofAmerica, an idea born in revolution, and renewed through two centuries of challenge, an idea tempered by the knowledge that but for fate, we, the fortunate and the unfortunate, might have been each other; an idea ennobled by the faith that our nation can summon from its myriad diversity, the deepest measure of unity; an idea infused with the conviction thatAmerica’s long, heroic journey must go forever upwarD、
