Epictetus

“It is not things that disturb us, but the views we take of them.”

“Some things are up to us and some are not. All peace begins with telling the two apart.”

“Do not ask that things happen as you wish. Wish them as they happen, and your life will run calmly.”

“We have two ears and one mouth so that we listen twice as much as we speak.”

“Do not talk about how a good person should be. Be one.”
