The most important thing is to be happy with what you're doing.

如果你没有至少90%的时间失败，那么你的目标还不够高。

A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else. Men’s happiness or misery is most part of their own making. He, whose mind directs not wisely, will never take the right way; and he, whose body is crazy and feeble, will never be able to advance in it.

无论大自然为人类准备了什么，无论多么不愉快，人类都必须接受，因为无知从来都不比知识更好。

在观察的领域里，机遇只青睐有准备的头脑。
