The following quote comes from a speech that United States Senator Barack Obama gave to the 2005 graduating class of Knox College in Galesburg IL:
"Focusing your life solely on making a buck shows a poverty of ambition. It asks too little of yourself. You need to take up the challeges that we face as a nation and make them your own, not because you have an obligation to those who are less fortunate, although you do have that obligation . . . Because it is only when you hitch your wagon to something larger than yourself that you realize your true potential."
