世界不是一个需要解决的问题；它是我们所属的一个生命体。
The world is not a problem to be solved; it is a living being to which we belong.
If you want to get smart, the question you have to keep asking is 'why, why, why?'
Leadership is about making tough decisions today that will benefit future generations.
Pain can be a form of knowledge.
The truth is rarely pure and never simple.
