The only thing that interferes with my learning is my education.
The highest knowledge is the knowledge of the self.
The farmer is the only man in our economy who buys everything at retail, sells everything at wholesale, and pays the freight both ways.
The real world is the most abstract thing of all.
如果你没有失败,说明你不够努力。
我总是在寻找新的挑战,新的方式来推动自己的创造力。
