你知道的越多，你就越意识到你不知道的越多。

我不需要理由去快乐。

We want to build technology that everybody loves using, and that affects everyone. We want to create beautiful, intuitive services and technologies that are so incredibly useful that people use them twice a day. Like they use a toothbrush. There aren’t that many things people use twice a day.

Courage to fail is just as important as the will to succeed.

In the end, all we have are words.

The only way to find true happiness is to risk being completely cut open.

激情让音乐焕发生命。
