Frase de Epicteto

“No man is free who is not master of himself.”

“It is impossible for a man to learn what he thinks he already knows.”

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

“If you want to improve, be content to be thought foolish and stupid with regard to external things.”

“Men are disturbed not by things, but by the view which they take of them.”
