把这一句，留给此刻的你
Every man gets a narrower and narrower field of knowledge in which he must be an expert in order to compete with other people. The specialist knows more and more about less and less and finally knows everything about nothing.
每个人的知识领域都越来越狭窄，要想与其他人竞争，他必须成为其中的一名专家。专家知道的越来越多，知道的越来越少，最后什么都不知道。
