We don't inherit the land from our ancestors; we borrow it from our children.

真相是，我们都有自己的监狱，而钥匙总是在触手可及的地方。

The world is full of people who will tell you what you can't do. You don't need them. You already know what you can't do. What you need is someone to tell you what you can.

译文：一个人处世应该时刻反思自己的言行，因为祸福如影随形。赏析：善恶随人作，祸福自己招。处事要多反思自己的言行是否得当，因为祸福就在转瞬之间发生。

I don't compete with anyone but myself. My goal is to be better than I was yesterday.

物理学家必须能够想象。
