不要执迷不悟。很多人都把犯错当成义务。既然已经走错路，他们就要继续走下去，以证明自己性格坚强。他们内心其实后悔犯错，在外却为自己的错误开脱。在他们刚开始犯错时，别人以为他们是粗心；到后来，就会被看作是愚蠢。轻率的承诺或者错误的决定不应该阻碍我们去改过，但是，有的人固守自己的愚蠢，宁愿做永远的傻瓜。
do not follow up a folly. many make an obligation out of a blunder, and because they have entered the wrong path they think it proves their strength of character to go on in it. within they regret their error, while outwardly they excuse it. at the beginning of their mistake they were regarded as inattentive, in the end as fools. neither an unconsidered promise nor a mistaken resolution are really binding. yet some continue in their folly and prefer to be constant fools.
