"Since it is not possible to get rid of the fear of death without knowledge of the universe, we cannot enjoy unmixed pleasure."

"The one who least needs tomorrow will most gladly greet tomorrow."

"We must, therefore, be careful how we choose our pleasures, and how we avoid our pains."

"Do not spoil what you have by desiring what you have not; remember that what you now have was once among the things you only hoped for."

"The truly wise man is he who does not grieve for what he has not, but rejoices in what he has."
