子曰:“學(xué)而時(shí)習(xí)之，不亦說乎?有朋自遠(yuǎn)方來，不亦樂乎?人不知而不慍，不亦君子乎?”

Confucius remarked, "It is indeed a pleasure to acquire knowledge and, as you go on acquiring, to put into practice what you have acquired. A greater pleasure still it is when friends of congenial minds come from afar to seek you because of your attainments. But he is truly a wise and good man who feels no discomposure even when he is not noticed of men."
