投资者应避免试图预测市场；这是徒劳的。
合作是关键，伟大的科学从来不是孤立完成的。
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.
