太阳必须落下才能升起。

文明的冲突将主宰全球政治。文明之间的断层将成为未来的战线。

The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life. You can turn over a new leaf every hour if you choose.

The thrill of discovery never gets old.

永远不要忘记你是一个独一无二的存在，你的存在本身就是一种奇迹。
