每日原则：区别心态开放和心态封闭的人

心态开放的人通过问问题学习。他们知道，与未知领域相比，他们已知的实在微不足道，而且可能是错误的。他们乐于身边有很多比自己知识渊博的人，从而可以有学习的机会。而心态封闭的人总是告诉你他们所知甚多，哪怕他们一无所知。如果身边有人比他们知识渊博，他们就会感到不安。

Open-minded people seek to learn by asking questions; they realize how little they know in relation to what there is to know and recognize that they might be wrong; they are thrilled to be around people who know more than they do because it represents an opportunity to learn something. Closed-minded people always tell you what they know, even if they know hardly anything. They are typically uncomfortable being around those who know a lot more than they do.
