陌生人与我们接近，因为我们在他们和我们自己之间感受到民族、社会、职业或一般人类本性的共同特征。他们远离我们，因为这些共同特征超越了他们或我们，并且只因为它们连接了许多人而连接我们。

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.

效率和道德必须齐头并进；没有另一方，任何一方都无法蓬勃发展。
