If you're not failing every now and again, it's a sign you're not doing anything very innovative.

"The world is full of obvious things which nobody by any chance ever observes."

The poet is the only one for whom the world is not silent; he is the only one who can hear the music of the spheres.

Life is like a song, with highs and lows.

半夜三更所想的事与清晨八时所想的事情太不一样。

The desire for recognition is a fundamental human need.

You must be the change you wish to see in the world.

翻译：贤明的君主和将领，之所以一出兵就可以战胜敌人，成就的功业超过一般人，是因为他们能事先探明敌情。事先探明敌情，不能使用占卜的手段获取，不可用类比的方法获取，也不可推验日月星辰运行来获取。一定要取之于人，取之于了解敌情的人。
