世界的真正历史是伟人的历史。
The true history of the world is the history of great men.
The meaning of earthly existence lies not, as we have grown used to thinking, in prospering but in the development of the soul.
Icame，Isaw，Iconquered.

We have a responsibility to future generations to leave the planet in better shape than we found it.
我们有责任为子孙后代留下一个比我们发现时更好的地球。
