Epictetus — "Seek not to have things happen as you wish, but wish things to happen as they do…"

"The greater the difficulty, the more glory in surmounting it. Skillful pilots gain their reputation from storms and tempests."

"Freedom isn't secured by filling up on your heart's desire but by removing your desire."

"When you have to deal with a man who is angry, remember that he is not angry with you, but with himself; he is only venting his anger on you."

"For where you find unrest, grief, fear, frustrated desire, failed aversion, jealousy and envy, happiness has no room for admittance. And where values are false, these passions inevitably follow."

"What, then, is the proper thing to do? To make the best of what is in our power, and take the rest as it naturally happens."
