“Working hard is important, but there's something that matters even more. Believing in yourself. Think of it this way: Every great wizard in history has started out as nothing more than we are now. Students. If they can do it, why not us?”

“I dreamed I was buying new shoes last night," said Ron. "What d'ya think that's gonna mean?""Probably that you're going to be eaten by a giant marshmallow or something," said Harry.”

“I hope you're pleased with yourselves. We could all have been killed - or worse, expelled. Now if you don't mind, I'm going to bed.”

“Everybody finished the song at different times. Dumbledore conducted their last few lines with his wand and when they had finished, he was one of those who clapped loudest. 'Ah music,' he said, wiping his eyes. 'A magic beyond all we do here!”

“Your qualifications, your CV, are not your life, though you will meet many people of my age and older who confuse the two.”

“Do you remember me telling you we are practicing non-verbal spells, Potter?""Yes," said Harry stiffly."Yes, sir.""There's no need to call me "sir" Professor."The words had escaped him before he knew what he was saying.”

“(...) “to have a hairy heart” has passed into everyday wizarding language to describe a cold or unfeeling witch or wizard.”

“Now you might think that I chose my second theme, the importance of imagination, because of the part it played in rebuilding my life, but that is not wholly so. Though I personally will defend the value of bedtime stories to my last gasp, I have learned to value imagination in a much broader sense. Imagination is not only the uniquely human capacity to envision that which is not, and therefore the fount of all invention and innovation. In its arguably most transformative and revelatory capacity, it is the power that enables us to empathise with humans whose experiences we have never shared.”

“What an idiot.”

“The truth." Dumbledore sighed. "It is a beautiful and terrible thing, and should therefore be treated with great caution.”

“Ron: Why spiders? Why couldn't it be "follow the butterflies?”

“The spells are made up. I have met people who assure me, very seriously, that they are trying to do them, and I can assure them, just as seriously, that they don’t work.”

“Come on!' he muttered, staring about. 'Where are you? Dad, come on--" But no one came. Harry raised his head to look at the circle of dementors across the lake. One of them was lowering its hood. It was time for the rescuer to appear--but no one was coming to help this time-- And then it hit him--he understood. He hadn't seen his father--he had seen himself--... 'It was stupid, thinking it was him,' he (Harry) muttered. 'I mean, I knew he was dead.' 'You think the dead we loved ever truly leave us? You think that we don't recall them more clearly than ever in times of great trouble? Your father is alive in you, Harry, and shows himself most plainly when you have need of him. How else could you produce that particular Patronus? Prongs rode again last night.'... 'You know, Harry, in a way, you did see your father last night...You found him inside yourself.' And Dumbledore left the office, leaving Harry to his very confused thoughts.”

“He didn't realize that love as powerful as your mother's for you leaves its own mark.”

“The realization of what would happen next settled gradually over Harry in the long minutes, like softly falling snow."I've got to go back, haven't I?""That is up to you.""I've got a choice?""Oh yes." Dumbledore smiled at him. "We are in King's Cross, you say? I think that if you decided not to go back, you would be able to…let's say…board a train.""And where would it take me?""On," said Dumbledore simply.”

“You haven't got a letter on yours," George observed. "I suppose she thinks you don't forget your name. But we're not stupid-we know we're called Gred and Forge.”

“Bad news, Harry. I've just been to see Professor McGonagall about the Firebolt. She – er, got a bit shirty with me. Told me I'd got my priorities wrong. Seemed to think I cared more about winning the Cup than I do about staying alive. Just because I told her I didn't care if it threw you off, as long as you caught the Snitch first.”

“By all means continue destroying my possessions. I daresay I have too many.”

“Do I look stupid?" snarled Uncle Vernon, a bit of fried egg dangling from his bushy mustache.”

“It is not our abilities that show who we truly are, it is our choices.”
