Propaganda is to a democracy what the bludgeon is to a totalitarian state.

Success comes from solving real problems, not just chasing trends.

艺术不是反映现实的镜子，而是塑造现实的锤子。

Always be learning. The world changes fast, and you need to keep up.

The strongest is never strong enough to be always the master， unless he transforms strength into right， and obedience into duty.
