知者之举事也，满则虑嗛，平则虑险，安则虑危，曲重其豫，犹恐及其祸，是以百举而不陷也。· A man of wisdom is very cautious in taking action. He keeps modesty in mind when he enjoys satisfaction; he keeps difficulties in mind when the action develops smoothly; he keeps perils in mind when he is at ease. Although he is already very cautious，yet he still worries about the possibility of unexpected misfortune. In so doing，he will not lose in a hundred actions.
