世界上有开朗的悲观主义者吗？我就是这样的人。

The light constantly changes, and that alters the atmosphere and beauty of things every minute.

星星真美，因为有一朵看不见的花。

数学是过去与未来的对话。

Silence remains, inescapably, a form of speech.

The biggest risk is not taking any risk. In a world that is changing quickly, the only strategy that is guaranteed to fail is not taking risks.

时间是最好的作者：它总能找到一个完美的结局。
