the important consideration is not your opponents, but yourself. It is bad to scream at them, not because it hurts them, they ought to be hurt, but because it hurts you. Anger is a form of recognition. It amounts to admitting that those people are important to you and that they have the power to hurt you. Actually, they haven't.
Ayn RandAt first, man was enslaved by the gods. But he broke their chains. Then he was enslaved by the kings. But he broke their chains. He was enslaved by his birth, by his kin, by his race. But he broke their chains. He declared to all his brothers that a man has rights which neither god nor king nor other men can take away from him, no matter what their number, for his is the right of man, and there is no right on earth above this right. And he stood on the threshold of freedom for which the blood of the centuries behind him had been spilled.
Ayn RandAn attempt to achieve the good by force is like an attempt to provide a man with a picture gallery at the price of cutting out his eyes.
Ayn RandNot selfishness, but precisely the absence of a self. Look at them. The man who cheats and lies, but preserves a respectable front. He knows himself to be dishonest, but others think heโs honest and he derives his self-respect from that, second-hand. The man who takes credit for an achievement which is not his own. He knows himself to be mediocre, but heโs great in the eyes of others.
