When men hate or blame you, or say hurtful things about you, look deeply into their hearts and see what kind of men they are. You'll see how unnecessary it is to strain after their good opinion. Yet you must still think kindly of them. they are your neighbors. The gods help them as they do you, by dreams and oracles, to win their hearts' desires.
Marcus AureliusConsider when thou art much vexed or grieved, that man's life is only a moment, and after a short time we are all laid out dead.
Marcus AureliusStop whatever you're doing for a moment and ask yourself: Am I afraid of death because I won't be able to do this anymore?
Marcus AureliusFor nowhere either with more quiet or more freedom from trouble does a man retire than into his own soul, particularly when he has within him such thoughts that by looking into them he is immediately in perfect tranquility; and I affirm that tranquility is nothing else than the good ordering of the mind.
Marcus Aurelius
