“It is you, the young and fearless at heart, who the nation is waiting to follow.”

That’s what America is. Not stock photos or airbrushed history, or feeble attempts to define some of us as more American than others. We respect the past, but we don’t pine for the past. We don’t fear the future; we grab for it. America is not some fragile thing. We are large, in the words of Whitman, containing multitudes. We are boisterous and diverse and full of energy, perpetually young in spirit. That’s why someone like John Lewis at the ripe old age of 25 could lead a mighty march.

And that’s what the young people here today and listening all across the country must take away from this day. You are America. Unconstrained by habit and convention. Unencumbered by what is, because you’re ready to seize what ought to be.

For everywhere in this country, there are first steps to be taken, there’s new ground to cover, there are more bridges to be crossed. And it is you, the young and fearless at heart, the most diverse and educated generation in our history, who the nation is waiting to follow.
