孔子说：“我曾整天不吃、整夜不睡，来思考。结果没好处，还不如学习。”

我认为在生活中拥有幽默感很重要。它帮助你度过艰难的时刻。

States are rational actors, and they will always act in their own self-interest.

Train employees well enough they could get another job， but treat them well enough so they never want to.

Never underestimate the power of a single idea to transform the world.

那是一种内在的东西，他们到达不了，也无法触及的，那是你的。
