What disturbs people, these are not things, but the judgments relating to things
Events do not just happen, but arrive by appointment.
It is not he who reviles or strikes you who insults you, but your opinion that these things are insulting.
Man is not fully free unless he is master of himself.
Ask yourself: Does this appearance (of events) concern the things that are within my own control or those that are not? If it concerns anything outside your control, train yourself not to worry about it.
It is not things in themselves which trouble us, but our opinions of things.
