使用您所拥有的。总是找到您所拥有的用途。永远不要保证您无法交付的东西，如果可能的话，请始终与微笑和友好的词达成协议。这个建议使他一生都为他服务。
(use what you've got. Always find a use for what you've got. Never promise what you can't deliver, and always do a deal with a smile and a friendly word if possible. That advice had served him in good stead all his working life.)
