《北史·列传·卷四十四》
所以，有所举措，必须分析事情每个微小的环节；有所行动，一定在细枝末节上小心谨慎。考虑得细致周到，失败就会少；既观察又谨慎，好运气就会到来。
言之不善，行之不正，鬼执强梁，人囚径廷，幽夺其魄，明夭其命。
So, for any action, we must analyze every tiny element of the matter; for any movement, we must be cautious at the slightest details. The more detailed we consider something, the less likely we are to fail; if we are both observant and cautious, good fortune will come.
