"Not that I would not, if I could, be both handsome and fat and well-dressed and a great athlete, and make a million a year; be a wit, a bon-vivant, and a lady-killer, as well as a philosopher; a philanthropist, statesman, warrior, and African explorer, as well as a ‘tone-poet’ and saint. But the thing is simply impossible. The millionaire’s work would run counter to the saint’s; the bon-vivant and the philanthropist would trip each other up; and the philosopher and the lady-killer could not well keep house in the same tenement of clay. So the seeker of his truest, strongest, deepest self must review the list carefully, and pick out the one on which to stake his salvation."
— William James in The Principles of Psychology.
