There are more men ennobled by study than by nature.
Every stage of human life, except the last, is marked out by certain and defined limits; old age alone has no precise and determinate boundary.
Let every man practice the art that he knows best.
Our minds are rendered buoyant by exercise.
Sweet is the memory of past troubles.
Nobody can give you wiser advice than yourself; you will never err if you listen to your own suggestions.
