这种我们能创造一个每个人的能力都忠实地被分级，好的就到顶端，坏的就到底部，而且保证过程毫无差错，这是不可能的。这世上有太多偶然的契机，不同的机运，出身，疾病，从天而降的意外等等，我们却无法将这些因素分级，无法完全忠实的将人分级。
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.
Change is hardest at the beginning, messiest in the middle, and best at the end.
The key to successful investing is to have the right temperament.
The good times of today, are the sad thoughts of tomorrow.
The best way to predict the future is to invent it.
如果你想拥有从未拥有的东西，就必须愿意做从未做过的事。
