Epictetus

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

“The essence of philosophy is that a man should so live that his happiness shall depend as little as possible on external things.”

“First learn the meaning of what you say, and then speak.”

“To accuse others for one's own misfortunes is a sign of want of education. To accuse oneself shows that one's education has begun. To accuse neither oneself nor others shows that one's education is complete.”

“Freedom is the right to live as we wish.”
