在这个希望你做任何事而不是阅读的世界里，阅读是一种反叛行为。
The idea that we will make a society where literally everybody is graded, the good at the top, bad at the bottom, exactly done as it should be, is impossible. There are simply too many random factors: accidents, accidents of birth, accidents of things dropping on people's heads, illnesses, etc. We will never get to grade them, never get to grade people as they should.
Success is not about how much money you make, it’s about the difference you make in people’s lives.
我总是很高兴地想到，我的教育大部分是非正式的，并且根植于土壤之中。
I don't take anything for granted.
