Epictetus

“Disease is an impediment to the body, but not to the will.”

“In every act, look to the end.”

“Consider first what the matter is, then your own nature, whether you can bear it.”

“At every accident remember to turn toward yourself and inquire what faculty you have for its use.”

“If anyone speaks ill of you, do not make excuses about what is said of you.”

“But answer: 'He was ignorant of my other faults, else he would not have mentioned only these.'”

“It is the act of an ill-instructed man to blame others for his own bad condition.”

“He who has begun to find fault with himself is on the way to wisdom.”

“He who blames neither himself nor others, is wise.”

“Don't seek for everything to happen as you wish; rather, wish that everything happen as it actually will.”

“Then your life will flow well.”

“Remember that the offense lies not in what is said but in your reaction.”

“Reflect on the patience that you have shown in vain pursuits, and resolve henceforth to spend it on what is real.”

“It is the act of a wise man neither to grieve for what he has not, nor to scorn what he has.”

“Behave well in the part assigned to you.”

“Hold what you have firmly, with no eye on what you have not.”

“Whoever then would be free, let him wish nothing or avoid nothing that is not in his control.”

“Wish only for what is in your control to wish, and avoid only what is in your control to avoid.”

“This is the only way to true peace.”
