每天都不能大意。命运总喜欢恶作剧，只要有可乘之机，它就会出其不备地攻击我们。我们的智慧、审慎、勇气甚至美貌，都要时刻准备接受它的考验。因为轻信之日，就会是受辱之时。最需小心的时候，总是不小心。粗心大意让我们失足，并因此而毁灭。所以，别人就采取这个策略，在我们大意之时考验我们是否完美。他们在阅兵的日子放过我们，只是冷眼旁观，却选择最意外的一天，让我们的英勇得到最严格的考验。
have no careless days. fate loves to play tricks, and will heap up chances to catch us unawares. our intelligence, prudence, and courage, even our beauty, must always be ready for trial. for their day of careless trust will be that of their discredit. care always fails just when it was most wanted. it is thoughtlessness that trips us up into destruction. accordingly it is a piece of military strategy to put perfection to its trial when unprepared. the days of parade are watched and are allowed to pass by, but the day is chosen when least expected so as to put valour to the severest test.
