There are some things so serious you have to laugh at them.

I don’t let mistakes discourage me, I let them educate me.

The goal of education is not to increase the amount of knowledge but to create the possibilities for a child to invent and discover, to create men who are capable of doing new things.

"To understand the future, one must first understand the past."

不要赔钱！！！客观地评估每个机会的风险。

真正的艺术家永远是美的仆人。
