A young man asks an old man：

“What’s the most valuable in the world？”

“Advice.”

“Then what’s the least valuable？”

“Advice.”

The young man begins to laugh.

“Isn’t that a truth？”says the old man，“When someone adopts your advice，it will be so useful. But when no one believes it，it will useless at.”

一個(gè)年輕人問一位老者：

“先生，世界上什么最有價(jià)值？”

“忠告?！?/p>

“那么，什么最沒有價(jià)值？”

“忠告?！?/p>

年輕人哈哈大笑。

老者說：“難道不是嗎？‘忠告’被人接納時(shí)，就是無價(jià)之寶；如果它不被人們所接納時(shí)，它就一文不值了。”
