You have to believe in the impossible.

聪明智慧的人，要保持着敦厚拙朴的态度，不可锋芒毕露；功高盖世的人，要保持着谦虚礼让的态度，不可居功自傲。勇猛无敌的人，要保持着小心谨慎的态度，不可无所忌惮；拥有巨财的人，要保持着如有不足的态度，不可张狂放肆。

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.
