"The great secret that all old people share is that you really haven't changed in seventy or eighty years. Your body changes, but you don't change at all."

译文：生下来就知道的人很少，学习后才知道的人很多。赏析：这个社会没有天才，所谓的天才都是通过后天的学习和努力。人不去学习，就会愚钝不开，只有不断地学习才会明白世间的真理。

Sustainable development requires not only vision but also concrete actions.

最好的领导者多听少说。

创新是解决今天和明天挑战的关键。

聪明的人心里明白而言语不必太多。
