写作是一种乐观的行为。如果你觉得这无关紧要，你就不会费心去做。
The act of writing is an act of optimism. You would not take the trouble to do it if you felt it didn't matter.
The role of the writer is to be a witness, to give voice to those who cannot speak for themselves.
我们这个时代的巨大挑战是创建一个既公正又可持续的世界秩序。
There is no shortcut to success, only down-to-earth efforts.
