不管我们了不了解历史，历史都是我们的一部分。
History lives in us, whether we learn it or not.
Hope is not a feeling; it is a doable thing.
The world is a mosaic of fleeting moments, each one precious in its own right.
生产与保护之间的平衡很微妙，但可以实现。
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.
We are what we repeatedly do. Excellence, then, is not an act, but a habit.
