心灵是真正的教育器官。

A book is a dream that you hold in your hand.

阅读的魔力在于它让我们可以活出一千种人生。

That day, for no particular reason, I decided to go for a little run. So I ran to the end of the road, and when I got there, I thought maybe I'd run to the end of town. And when I got there, I thought maybe I'd just run across Greenbow County. Now, I figured since I'd run this far, maybe I'd just run across the great state of Alabama. And that's what I did. I ran clear across Alabama. No particular reason. I just kept on going. I ran clear to the ocean. And when I got there, I figured since I'd gone this far, might as well turn around, just keep on going. And when I got to another ocean, I figured since I'd gone this far... I might as well just turn back and keep right on going. When I got tired, I slept. When I got hungry, I ate. When I had to go... you know... I went.

The greatest wisdom is knowing that you know nothing.

Change is inevitable; how you respond defines your success.

科学的进步在于每一步发现一种新的秩序，这种秩序将看似不同的事物统一起来。
