可持续性不是一种选择，而是我们对下一代的责任。

I don't think you can ever really change who you are, but you can change how you live your life.

The past is a story we tell ourselves.

The chess-board is the world; the pieces are the phenomena of the universe; the rules of the game are what we call the laws of Nature.  

成功的基础建立在团队的力量和材料的质量之上。
