环境管理不是可选的——这是我们对后代的责任。

自由的代价是永恒的警惕。

The world is before you, and you need not take it or leave it as it was when you came in.

"Memory is a strange thing, it doesn't work like a camera or a tape recorder, it reconstructs things, it edits the past with the scissors of the present."

The eye through which I see God is the same eye through which God sees me; my eye and God's eye are one eye, one seeing, one knowing, one love.

To enjoy freedom we have to control ourselves.

创新不仅仅是创造新产品，而是重新构想整个体验。
