可持续性不是一种选择——它是我们对后代的责任。

The past is a foreign country; they do things differently there.

永远不要让任何人让你觉得你不配得到你想要的。

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.
