Happiness is like a butterfly; the more you chase it, the more it will elude you. But if you turn your attention to other things, it will come and sit softly on your shoulder.

Leadership is about making tough decisions today that will shape a better tomorrow.

Success is not final, failure is not fatal: it is the courage to continue that counts.

The moment you give up, is the moment you let someone else win.

做伟大工作的唯一方法就是热爱你所做的事情。

I'm intimidated by the fear of being average. And I'm just not. I'm not average.

成功不是偶然的，而是通过不断的努力和坚持得来的。
