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.

You have to be able to laugh at yourself, or you'll never make it in this business.

You are not stuck where you are unless you decide to be.

可持续性已不再是一种选择——它是任何希望在将来蓬勃发展的企业的必要条件。
