人生最大的遗憾，莫过于轻易地放弃了不该放弃的，固执地坚持了不该坚持的。

"The best and most beautiful things in the world cannot be seen or even touched - they must be felt with the heart."

The most important thing in science is not so much to obtain new facts as to discover new ways of thinking about them.

用心管理的森林才能长久存在。

过去总是紧张的，而未来是完美的。
