“…but who can know the heart of a man? Not even he himself, I suspect. A man is the easiest animal to put on a leash, and the hardest to keep leashed. Even when he chooses it himself.”

“The person who does not know how to put up with others should retire into himself, if indeed he can suffer even himself.”

“It is not often that a man can make opportunities for himself. But he can put himself in such shape that when or if the opportunities come he is ready.”

“Man can acquire accomplishments or he can become an animal, whichever he wants. God makes the animals, man makes himself.”

“The man of action is not the headstrong fool who rushes into danger with no thought for himself, but the man who puts into practice the things he knows.”

“When a man begins to know himself a little he will see in himself many things that are bound to horrify him. So long as a man is not horrified at himself he knows nothing about himself.”

“Man lives measuring, and he’s the measure of nothing. Not even of himself.”

“"But to be hanged—is that not unendurable?" Even so, when a man feels that it is reasonable, he goes off and hangs himself.”

“Man is a make-believe animal — he is never so truly himself as when he is acting a part.”

“The great man is the man who can get himself made and who will get himself made out of anything he finds at hand.”
