Greatness is not about being the best, it's about being better than you were yesterday.
Stay humble, stay hungry.
Start by doing what's necessary; then do what's possible; and suddenly you are doing the impossible.
從做必要的事情開(kāi)始；然后做可能的事情；突然間你就在做不可能的事情了。
"There's nothing that says you have to be happy all the time."
