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.

唯一具有持久重要性的自由是智慧的自由，也就是说，为了本质上值得的目的而行使的观察和判断的自由。

成功不在于成为最好的，而在于成为最能适应的。

当你为他人的看法而活时，你就已经死了。
