我是一个非常积极的思想家，我认为这是我在困难时刻最能帮助我的东西。
I’m a very positive thinker, and I think that is what helps me the most in difficult moments.
I believe that man will not merely endure: he will prevail. He is immortal, not because he alone among creatures has an inexhaustible voice, but because he has a soul, a spirit capable of compassion and sacrifice and endurance.
We don’t just mine stone; we shape the foundations of communities.
不要再担心可能会出错的事情，开始对可能会顺利的事情感到兴奋。
