One day a father was teaching his son and said, "The keys to your success are keeping your word and cleverness. Once you give somebody a promise, you must carry it out on matter what will happen. This is called 'keeping one's words.'
    "What is cleverness? asked his son.
    "Cleverness is that you'll never make such a promise, " the father answered.
    一天，父親教育兒子說：“一個人成功的關鍵就是嚴守諾言和足夠聰明。一旦你給了別人承諾，無論發(fā)生什么事，你都得實現(xiàn)它，這個就叫‘守諾言’?！?BR>    兒子問：“那么什么是聰明呢？”
    父親回答：“聰明就是任何時候都別做這樣的承諾。”
