Focusing your life solely on making a buck shows a certain poverty of ambition. It asks too little of yourself. Because it's only when you hitch your wagon to something larger than yourself that you realize your true potential.

Tonight, we gather to affirm the greatness of our nation—not because of the height of our skyscrapers, or the power of our military, or the size of our economy. Our pride is based on a very simple premise, summed up in a declaration made over two hundred years ago: "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain inalienable rights, that among these are life, liberty and the pursuit of happiness." That is the true genius of America—a faith in simple dreams, an insistence on small miracles.

Someone once wrote, “A bullet need happen only once, but for peace to work we need to be reminded of its existence again and again and again.” My fellow Americans, only we can prove, through words and through deeds, that we will not be divided. And we’re going to have to keep on doing it “again and again and again.” That’s how this country gets united. That’s how we bring people of good will together. Only we can prove that we have the grace and the character and the common humanity to end this kind of senseless violence, to reduce fear and mistrust within the American family, to set an example for our children. That’s who we are, and that’s who we always have the capacity to be. And that’s the best way for us to honor the sacrifice of the brave police officers who were taken from us this morning.
