When you see this on your flist, quote The West Wing
Bartlet: There's a promise I ask everyone who works here to make: Never doubt that a small group of thoughtful and committed citizens can change the world. Do you know why?
Will: It's the only thing that ever has.
Leo: ...Because I'm tired of it: year after year after year after year having to choose between the lesser of who cares. Of trying to get myself excited about a candidate who can speak in complete sentences. Of setting the bar so low, I can hardly bear to look at it. They say a good man can't get elected President. I don't believe that. Do you?
I love both these quotes, because they embody what I most loved about the show; its optimism and its faith in the power of dedicated, thinking people to make the world a better place for everyone.
