Darkness cannot drive out darkness； only light can do that.Hate cannot drive out hate； only love can do that.

Quality should never be compromised for the sake of speed.

和平不是没有战争，而是正义的胜利。

我们越了解自己的偏见，就越能利用它们为自己服务。

真正的自由来自心灵的解放。

"It's the possibility of having a dream come true that makes life interesting."

"The truth is not in the facts, but in the way we tell them."
