"The true sign of intelligence is not knowledge but imagination."

It is hard to imagine a more stupid or more dangerous way of making decisions than by putting those decisions in the hands of people who pay no price for being wrong.

The best decisions are made when you listen to diverse perspectives.

译文：少年不知道早起勤奋学习，到老了后悔读书少就太迟了。赏析：人在年轻时，精力旺盛，正是勤奋读书，努力奋斗的时候。

The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.

应该引导孩子通过自己的活动去发现真理。
