You are never too old to set another goal or to dream a new dream.

The best way to predict the future is to create it.

We must balance short-term demands with long-term sustainability.

There are no hard distinctions between what is real and what is unreal, nor between what is true and what is false. A thing is not necessarily either true or false; it can be both true and false.

做人的气度要高旷但不可疏漏狂妄；心思要缜密但不可琐碎；趣味要淡但不可枯燥；操守要严明但不可激烈。
