F. Scott Fitzgerald, in a letter to his daughter Scottie at college:

“Once one is caught up into the material world, not one person in ten thousand finds the time to form literary taste, to examine the validity of philosophic concepts for himself or to form what, for lack of a better phrase, I might call the wise and tragic sense of life.

By this I mean the thing that lies behind all great careers, from Shakespeare’s to Abraham Lincoln’s, and as far back as there are books to read—the sense that life is essentially a cheat and its conditions are those of defeat, and that the redeeming things are not “happiness and pleasure” but the deeper satisfactions that come out of struggle. Having learned this in theory from the lives and conclusions of great men, you can get a hell of a lot more enjoyment out of whatever bright things come your way.”
