真正的领导力是为他人服务，而不是为自己。
True leadership is about serving others, not yourself.
The truth doesn’t set you free, it just makes you see the chains.
I am not a hero of mathematics. I'm not even that successful; that is why I don't want to have everybody looking at me.
Quality is not a luxury; it is a necessity.
在数学中，真理总是相对于你所在的系统而言的。
