绝不要和愚蠢的人争论，他们会把你拖到他们那样的水平，然后回击你。
I can never be safe; I always try and go against the grain. As soon as I accomplish one thing, I just set a higher goal. That’s how I’ve gotten to where I am.
——在柏林墙演说
The opera is a beautiful and irrational world. One could spend a lifetime listening and still not understand everything.
No man's knowledge here can go beyond his experience.
