Always forgive your enemies; nothing annoys them so much.

You are always a valuable, worthwhile human being — not because anybody says so, not because you're successful, not because you make a lot of money — but because you decide to believe it and for no other reason.

可持续性不是一种选择；它是我们对后代的责任。

根本不稳固必然会央及枝叶。行为不守信必然会损害声誉。

科学的全部不过就是日常思考的提炼。
