The ideas of economists and political philosophers， both when they are right and when they are wrong， are more powerful than is commonly understood. Indeed the world is ruled by little else. Practical men， who believe themselves to be quite exempt from any intellectual influence， are usually the slaves of some defunct economist.

失败是有教益的。真正思考的人从失败中学到的东西和从成功中学到的一样多。

你必须对你所做的事情充满热情。如果你没有热情，你就不会成功。

笑是一种连接大群体的机制。

写作很简单：你只需要坐在那里盯着一张白纸，直到额头上冒出鲜血。

谋划事情无主见，就会陷入困境；做事没有准备好，容易归于失败。

以真诚之心待人接物。
