世界的眼泪是恒定的。每当一个人开始哭泣，另一个地方就有一个人停止哭泣。笑声也是如此。
The tears of the world are a constant quantity. For each one who begins to weep, somewhere else another stops. The same is true of the laugh.
Nothing is more powerful than will, and nothing is more important than determination.
The best way to appreciate your job is to imagine yourself without one.
最终重要的不是我们找到的答案，而是我们敢于提出的问题。
我并不完美，我也不假装完美。
