理解布莱克-斯科尔斯模型的关键在于认识到它是基于创建无风险对冲的理念。

不被荣誉诱惑，不被诽谤吓退，遵循道义行事，认真端正自己。

Sit down before fact as a little child, be prepared to give up every preconceived notion, follow humbly wherever and to whatever abysses nature leads, or you shall learn nothing.  

I’m going to use all my tools, my God-given ability, and make the best life I can with it.

Never spend your money before you have it.
