求知若饥，虚心若愚。
The safest way to try and get what you want is to try and deserve what you want. It’s such a simple idea. It’s the golden rule so to speak. You want to deliver to the world what you would buy if you were on the other end.
有成就感的人会把世界看成一个友好的世界，并乐于看到它照原样保持下去，但失意者却会乐于看到世界急遽改变。
今天种下的每一棵树，都是对明天的承诺。
It's easier to stay out of trouble than it is to get out of trouble.
