Isn't it a pleasure to study and practice what you have learned? Isn't it also great when friends visit from distant places? If one remains not annoyed when he is not understood by people around him, isn't he a sage?
ConfuciusThere are three things which the superior man guards against. In youth ... lust. When he is strong ... quarrelsomeness. When he is old ... covetousness.
Confucius
