"But I hope you don’t walk away from the challenge. Focusing your life solely on making a buck shows a certain poverty of ambition. It asks too little of yourself. You need to take up the challenges that we face as a nation and make them your own. Not because you have a debt to those who helped you get here, although you do have that debt. Not because you have an obligation to those who are less fortunate than you, although I do think you do have that obligation. It’s primarily because you have an obligation to yourself. Because individual salvation has always depended on collective salvation. Because it’s only when you hitch your wagon to something larger than yourself that you realize your true potential."
Our potential and its realization lies in dreaming; it lies in believing that when one benefits, we all benefit. It lies in not taking the easy road abandoning everyone else in the process. I don't think there is much more I can say that the speaker has not said so well already. We are challenged, now it is our choice to face it. And like the slogan of old, something about together we live, divided we die.
