Stover at Yale by Owen Johnson

When Stover returned to college as a junior, he showed the results of his summer with Regan. He had gone into construction gangs, and learned to obey and to command. He had had a glimpse of what the struggle for existence meant in the stirring masses; and he had known the keenness of a little joy and the reality of sorrow to those for whom everything in life was real.

He had long ago surrendered the idea of entering Skull and Bones over the enmity of Reynolds and Le Baron, and this relinquishing somehow robbed him of all the awe that he had once felt. He had returned a man, tempered by knowledge of the world, distinguishing between the incidental in college life and the vital opportunity within his grasp.
