The greatest resource we have is human ingenuity.

变得更好的唯一方法是接受你并不像自己想象的那么好的想法。

The natural effort of every individual to better his own condition， when suffered to exert itself with freedom and security， is so powerful a principle that it is alone， and without any assistance， not only capable of carrying on the society to wealth and prosperity but of surmounting a hundred impertinent obstructions with which the folly of human laws too often encumbers its operations.

骄傲多半涉及我们对自己的看法，而虚荣则涉及我们希望别人如何看待我们。
