“Man is not worried by real problems so much as by his imagined anxieties about real problems”

“It is not so much what happens to you as how you think about what happens.”

“There is only one way to happiness and that is to cease worrying about things which are beyond the power or our will. ”

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

“God has entrusted me with myself. No man is free who is not master of himself. A man should so live that his happiness shall depend as little as possible on external things. The world turns aside to let any man pass who knows where he is going.”

“A guide, on finding a man who has lost his way, brings him back to the right path—he does not mock and jeer at him and then take himself off. You also must show the unlearned man the truth, and you will see that he will follow. But so long as you do not show it him, you should not mock, but rather feel your own incapacity.”

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