防备那些利用他人达到自己目的的人。只有提高警惕，才能防备他人诡计。要留意他人的意图。许多人都善于将自己的事变成别人的事。除非你能拥有洞察他人意图之钥匙，否则，无论在何时，你都有可能被迫为他们火中取栗，而伤害自己的手指。
watch him that begins with another's to end with his own. watchfulness is the only guard against cunning. be intent on his intentions. many succeed in making others do their own affairs, and unless you possess the key to their motives you may at any moment be forced to take their chestnuts out of the fire to the damage of your own fingers.
