"The animal is content if its physiological needs--its hunger, its thirst and its sexual needs--are satisfied. Insamuch as a man is also animal, these needs are likewise imperative and must be satisfied. But insamuch as a man is human, the satisfaction of these instinctual needs is not sufficient to make him happy; they are not even sufficient to make him sane.:
"First, have a definite, clear practical ideal; a goal, an objective. Second, have the necessary means to achieve your ends; wisdom, money, materials, and methods. Third, adjust all your means to that end.
"Every man dies, not every man really lives."
"How selfish of me, let's do all the things that YOU wanna do!"
"it is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied."
"All that I know is nothing - I'm not even sure of that."
