"Men are disturbed not by the things which happen, but by the opinions about the things."
"Seek not that the things which happen should happen as you wish; but wish the things which happen to be as they are, and you will have a tranquil flow of life."
"Whoever then wishes to be free, let him neither wish for anything nor avoid anything which depends on others: if he does not observe this rule, he must be a slave."
