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.

Never stop learning, because the world never stops changing.

想得大，想得长远。

创新来自于挑战现状并愿意承担风险。

尘世存在的意义，并不像我们习惯于认为的那样，在于繁荣昌盛，而在于灵魂的滋长。
