叶公问孔子于子路，子路不对。子曰：“女奚不曰。其为人也，发愤忘食，乐以忘忧，不知老之将至云尔。”
1The Duke of Sheh asked Tsze-lu about Confucius, and Tsze-lu did not answer him.
2The Master said, 'Why did you not say to him,-- He is simply a man, who in his eager pursuit (of knowledge) forgets his food, who in the joy of its attainment forgets his sorrows, and who does not perceive that old age is coming on?'
