But in the end, it's only a passing thing, this shadow. Even darkness must pass. A new day will come. And when the sun shines it will shine out the clearer. Those were the stories that stayed with you. That meant something, even if you were too small to understand why.
But I think Mr. Frodo, I do understand. I know now. Folk in those stories had losts of chances of turning back, only they didn't. They kept going, because they were holding on to something.
That there is some good in this world, and it's worth fighting for."
J.R.R. Tolkien - The Lord of the Rings (Samwise Gamgee)
