The greatest use of a life is to spend it for something that will outlast it.

If you don't fail at least 90 percent of the time, you're not aiming high enough.

I'm not a perfect person, I never claimed to be. But I'm trying every day to be better than I was yesterday.

成功是最好的报复。

技术突破需要长期投入和耐心，不能急功近利。
