国际体系本质上是竞争性的，国家不断试图互相超越。
The international system is inherently competitive, and states are constantly trying to outmaneuver each other.
The world is full of people whose notion of a satisfactory future is, in fact, a return to the idealised past.
The best preparation for tomorrow is doing your best today.
预测未来的最好方法就是创造未来。
不要等待机会，创造机会。
城市是一个伟大的人工制品，是人类文明的最高作品。
Innovation is the key to staying ahead in a competitive world.
