我只与自己竞争，不与任何人竞争。
I don't compete with anyone but myself.
I don't rap about my struggles, I rap about my victories.
The pursuit of knowledge is a journey without end, but each step brings its own rewards.
the only thing we have to fear is fear itself.
对于自己没有获得2009年诺贝尔奖的反应
The supreme happiness of life is the conviction that we are loved.
