The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.

The moral feeling of human nature is an obligation， and we must endow the soul with the sense of beauty.

I have always believed that technology should do the hard work – discovery, organization, communication – so users can do what makes them happiest: living and loving, not messing with annoying computers! That means making our products work together seamlessly.

继续前进，继续相信，永不放弃。

你的工作将占据你生活的很大一部分，唯一能真正满足的方法就是做你认为伟大的工作。
