The brain is a body part too; we just know less about it.

Hope is not blind optimism. It's not ignoring the enormity of the task ahead or the roadblocks that stand in our path. It's not sitting on the sidelines or shirking from a fight. Hope is that thing inside us that insists, despite all evidence to the contrary, that something better awaits us if we have the courage to reach for it, and to work for it, and to fight for it. Hope is the belief that destiny will not be written for us, but by us, by the men and women who are not content to settle for the world as it is, who have the courage to remake the world as it should be.

I do have an obligation to make sure that I am following some of the rules. I can't simply ignore laws that are out there.

That is the true genius of America-a faith in simple dreams, an insistence on small miracles.
