过去的已经过去，且一去不返，而聪明人总是努力着眼于现在和将来的事情，所以对过去耿耿于怀着无非是在捉弄自己罢了。 That which is past is gone, and irrevocable; and wise men have enough to do, with things present and to come; therefore they do but trifle with themselves, that labor in past matters.
不会在必要的情况下装傻的人，不是聪明人。 He is not a wise man who cannot play the fool upon occasions.
