I have never been able to write a happy play. I can't. I can write a funny play, but not a happy play.

Non-violence is the greatest force at the disposal of mankind.

If I waited for perfection, I would never write a word.

君子这样来造船车，所以属下都效法他，因此他的人民就会饥寒交迫，不得不做奸邪的事。奸邪的事情一多，刑罚就重，刑罚一重，国家就混乱。国君若真的希望天下太平而不希望天下大乱的话，如果要做船车，就不能不节俭。 

唯一受过教育的人是学会了如何学习和改变的人。

The best songs are the ones that come from the soul.
