效率是把事情做对，效果是做对的事情。

Failure gave me an inner security that I had never attained by passing examinations. Failure taught me things about myself that I could have learned no other way. I discovered that I had a strong will, and more discipline than I had suspected; I also found out that I had friends whose value was truly above the price of rubies.

世界上充满了门，每一扇门都是一个选择。

只要能够改变你自己的头脑，你就可以永远保持年轻。
