Ayn Rand, The Fountainhead

"Listen to what is being preached today. Look at everyone around us. You've wondered why they suffer, why they seek happiness and never find it. If any man stopped and asked himself whether he's ever held a truly personal desire, he'd find the answer. He'd see that all his wishes, his efforts, his dreams, his ambitions are motivated by other men. He's not really struggling even for material wealth, but for the second-hander's delusion - prestige. A stamp of approval, not his own. He can find no joy in the struggle and no joy when he has succeeded. He can't say about a single thing: 'This is what I wanted because I wanted it, not because it made my neighbors gape at me'. Then he wonders why he's unhappy."
