Let it judge that nothing is either bad or good which can happen equally to the bad man and the good. For that which happens equally to him who lives contrary to nature and to him who lives according to nature, is neither according to nature nor contrary to nature. – Marcus Aurelius
Live not as though there were a thousand years ahead of you. Fate is at your elbow; make yourself good while life and power are still yours. – Marcus Aurelius
A good deed is never lost. He who sows courtesy, reaps friendship; he who plants kindness, gathers love; pleasure bestowed on a grateful mind was never sterile, but generally gratitude begets reward. – St. Basil
A good conscience is to the soul what health is to the body; it preserves a constant ease and serenity within us, and more than countervails all the calamities and afflictions that can possibly befall us. – Joseph Addison
The beauty of the soul shines out when a man bears with composure one heavy mischance after another, not because he does not feel them, but because he is a man of high and heroic temper. – Aristotle
