“It is your duty to act well the part that is given to you; to choose it is another's.”

“When anything happens, the only thing in your power is to use it for your own profit.”

“Whoever does not act so is enslaved.”

“He is free who lives as he wishes to live.”

“Practice yourself, for heaven's sake, in little things; and thence proceed to greater.”

“Difficulties are things that show what people are.”

“For the future, when anything happens to you, remember that God is the trainer.”

“Now have you sent me, says God, into the world as a witness; you must be a witness to my majesty.”

“Until the most exalted dies a hero, he is born a slave.”

“What worries you, masters you.”

“Wealth consists not in having great possessions, but in having few wants.”

“He who fears death either fears the loss of sensation or a different kind of sensation.”

“You will not be afraid of any of these things.”

“He is unconquerable whom no event throws into perturbation.”

“Man is disturbed not by the things which happen, but by his opinions about the things.”

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

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

“Be silent for the most part, or, if you speak, say only what is necessary.”

“It's not what happens to you, but how you react to it that matters.”
