如果你看得足够久，平凡就会变得非凡。

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.

The only thing that makes life possible is permanent, intolerable uncertainty; not knowing what comes next.

如果易用性是唯一的要求，那么每个人都会还在骑三轮车。
