If a man is unhappy, remember that his unhappiness is his own fault, for God made all men to be happy.
Don't demand or expect that events happen as you would wish them do. Accept events as they actually happen. That way, peace is possible.
No man is disturbed by things, but by his opinion about things.
Events do not just happen, but arrive by appointment.
What is learned without pleasure is forgotten without remorse.
Bear in mind that you should conduct yourself in life as at a feast.
