The only thing I know is that I don't know anything.

Innovation starts with questioning the status quo.

Customer satisfaction is worthless. Customer loyalty is priceless.

A picture is a fact.

I was working at a financial firm in New York City with a bunch of very smart people， and I had a brilliant boss that I much admired. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park， listened carefully to me， and finally said， "That sounds like a really good idea， but it would be an even better idea for someone who didn't already have a good job." That logic made some sense to me， and he convinced me to think about it for 48 hours before making a final decision. Seen in that light， it really was a difficult choice， but ultimately， I decided I had to give it a shot. I didn't think I'd regret trying and failing. And I suspected I would always be haunted by a decision to not try at all. After much consideration， I took the less safe path to follow my passion， and I'm proud of that choice.

"The future is about making a difference."

一个人就是他所有不幸的总和。你以为不幸终会疲倦，但时间本身就是你的不幸。
