意识到社会结构的概念并敏感地使用它，就是能够在各种环境中追踪这种联系。
To be aware of the idea of social structure and to use it with sensibility is to be capable of tracing such linkages among a great variety of milieux.
Be less curious about people and more curious about ideas.
I'm not afraid of losing, I'm afraid of not giving my best.
真正的友情在困难时才会被考验。
