Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.

药物遇到同类之气才能成形，大道在虚无缥缈中与自然相合。

我们应该用结果来衡量成功，而不仅仅是投入。

Never let success get to your head or failure to your heart.

The past is a shadow that follows us everywhere.

As Will Rogers would have said, "There is no such thing as a free variable."

即使输了，我也能学到东西。
