我认为预测未来的最好方法就是创造它。
The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.
In the end, we will remember not the words of our enemies, but the silence of our friends.
知识不会使我们更丰富;它使我们越来越远离神秘世界——这个我们曾经的天然家园。
