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.

Leadership is about making tough decisions today that will benefit future generations.

Challenges are opportunities in disguise; embrace them and grow stronger.

强调资源、目标和取舍的重要性。
