"The best revenge is to be unlike him who performed the injury."

"How much more grievous are the consequences of anger than the causes of it."

"If you are distressed by anything external, the pain is not due to the thing itself, but to your estimate of it; and this you have the power to revoke at any moment."

"Do not act as if you were going to live ten thousand years. Death hangs over you. While you live, while it is in your power, be good."

"The art of living is more like wrestling than dancing, in that it stands ready against the accidental and the unforeseen, and is not apt to fall."
