You are not here merely to make a living. You are here in order to enable the world to live more amply, with greater vision, with a finer spirit of hope and achievement. You are here to enrich the world, and you impoverish yourself if you forget the errand.
Source: Address, "The Meaning of a Liberal Education," to the Federation of High School Teachers, New York, 9 January 1909
Genuinely Wilson, and the standard citation given for it is the January 1909 address to the New York high school teachers, reproduced in The Papers of Woodrow Wilson. I am reporting that citation from training memory and have not confirmed it against the primary text, so treat the source line as strong-but-unchecked rather than as a verified page reference. Attribution itself is not seriously disputed.
