《史记·七十列传·老子韩非列传》
君主对游说者的恩宠还没有达到深厚的程度，而游说的人把知心话全部说出来，如果意见被采纳实行而且见到了功效，那么，君主就会忘掉你的功劳；如果意见行不通而且遭到失败，那么游说者就会被君主怀疑，像这样，游说的人就会有危险。
周泽未渥也而语极知，说行而有功则德亡，说不行而有败则见疑，如是者身危。
If the monarch's favor of the lobbyist is not yet deeply rooted, and the lobbyist confides all their secrets, if the ideas are accepted and put into practice and are effective, the monarch will forget your achievement; if the ideas are not adopted and fail, the monarch will become suspicious of the lobbyist. In situations like this, the lobbyist will be in danger.
