世界總是危險(xiǎn)的，人們總是有好有壞。

The circumstances of the world are continually changing, and the opinions of man change also; and as government is for the living, and not for the dead, it is the living only that has any right in it.

創(chuàng)新不僅僅是關(guān)于技術(shù)；它是關(guān)于改變我們的生活方式。

我應(yīng)該，所以我能夠。

"Words are, of course, the most powerful drug used by mankind."
