政治不是理论，而是实践。

You can't run a business, or anything, on a theory.

I write songs because I'm fucked up in the head and need to get shit out.

身份是我们讲给自己听的故事，有时我们必须重写它。

What I’ve achieved in tennis is great, but who I am as a person is more important.

我曾经以为世界是按部落划分的。然后我以为它是按贫富划分的。然后我以为它是按愚蠢和聪明划分的。但现在我知道它是按活着的人和死去的人划分的。

We don't read and write poetry because it's cute. We read and write poetry because we are members of the human race. And the human race is filled with passion. Medicine, law, business, engineering: these are noble pursuits and necessary to sustain life. But poetry, beauty, romance, love...these are what we stay alive for.

Life is a journey, and love is what makes that journey worthwhile.
