Harry PotterIt was, he thought, the difference between being dragged into the arena to face a battle to the death and walking into the arena with your head held high. Some people, perhaps, would say that there was little to choose between the two ways, but Dumbledore knew - and so do I, thought Harry, with a rush of fierce pride, and so did my parents - that there was all the difference in the world.

"Happiness can be found, even in the darkest of times, if one only remembers to turn on the light."

"If you want to know what a man's like, take a good look at how he treats his inferiors, not his equals."

"It is the unknown we fear when we look upon death and darkness, nothing more."
- Albus Dumbledore, Harry Potter and the Half-Blood Prince
"Of course it is happening inside your head, Harry, but why on earth should that mean that it is not real?"
- Albus Dumbledore, Harry Potter and the Deathly Hallows
“It takes a great deal of courage to stand up to our enemies, but a great deal more to stand up to our friends.”

LOTR: 
All that is gold does not glitter.
Not all those who wander are lost.
The old that is strong does not wither.
Deep roots are not reached by the frost.
From the ashes a fire shall be woken,
A light from the shadows shall spring.
Renewed shall be blade that was broken:
The crownless again shall be king.
- The Riddle of Strider, The Fellowship of the Ring
"It's a dangerous business, Frodo, going out of your door, you step into the Road, and if you don't keep your feet, there is no telling where you might be swept off to."
- Bilbo Baggins, The Fellowship of the Ring
Frodo: I can't do this, Sam.
Sam: I know. It's all wrong. By rights we shouldn't even be here. But we are. It's like in the great stories, Mr. Frodo. The ones that really mattered. Full of darkness and danger, they were. And sometimes you didn't want to know the end. Because how could the end be happy? How could the world go back to the way it was when so much bad had happened? 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 lots of chances of turning back, only they didn't. They kept going. Because they were holding on to something.
Frodo: What are we holding onto, Sam?
Sam: That there's some good in this world, Mr. Frodo... and it's worth fighting for.
Sam: I wonder if we'll ever be put into songs or tales.
Frodo: [turns around] What?
Sam: I wonder if people will ever say, 'Let's hear about Frodo and the Ring.' And they'll say 'Yes, that's one of my favorite stories. Frodo was really courageous, wasn't he, Dad?' 'Yes, my boy, the most famousest of hobbits. And that's saying a lot.'
Frodo: [continue walking] You've left out one of the chief characters - Samwise the Brave. I want to hear more about Sam.
[stops and turns to Sam]
Frodo: Frodo wouldn't have got far without Sam.
Sam: Now Mr. Frodo, you shouldn't make fun; I was being serious.
Frodo: So was I.
[they continue to walk]
Sam: Samwise the Brave...

"Oh, you. You just couldn't let me go, could you? This is what happens when an unstoppable force meets an immovable object. You are truly incorruptible, aren't you? Huh? You won't kill me out of some misplaced sense of self-righteousness. And I won't kill you because you're just too much fun. I think you and I are destined to do this forever." - The Joker
"You see madness, as you know, is like gravity. All it takes is a little push!" - The Joker (love this one!)
Okay maybe 'quotes' might not be the right word for these, but I still consider them as quotes and they sure as hell stir up some emotions in me.
