The only limit to our realization of tomorrow is our doubts of today.
实现明天的唯一限制是我们今天的疑虑。
永远不要停止学习，因为世界从未停止变化。
What can be said at all can be said clearly; and whereof one cannot speak thereof one must be silent.
The best way to predict the future is to create it yourself.
世界如此美好又遗憾，你我皆是自远方而来的独行者，不断行走，不顾一切，哭着，笑着，留恋人间，只为不虚此行。
