"Hope springs forever."

"Don't count your owls before they are delivered."

"Have to? Of course you have to! But only because of you, Harry, won't rest until Voldemort is finished! Think now, for once, if you have never heard of the prophecy! What would you do?"

"That's chess!" snapped Ron. "You've got to make some sacrifices!"

"I am not worried, Harry," said Dumbledore, his voice a little stronger despite the freezing water. "I am with you."

"Where your treasure is, there will your heart be also"

"Rock bottom became the solid foundation on which I rebuilt my life."

"The mistake ninety-nine percent of humanity made, as far as Fats could see, was being ashamed of what they were; lying about it, trying to be somebody else."

"I am what I am, an’ I’m not ashamed. 'Never be ashamed,’ my ol’ dad used ter say, ‘there’s some who’ll hold it against you, but they’re not worth botherin’ with."

"What's most important in a friendship? Tolerance and loyalty."

"Call him Voldemort, Harry. Always use the proper name for things. Fear of a name increases fear of the thing itself."

"You must accept the reality of other people. You think that reality is up for negotiation, that we think it's whatever you say it is. You must accept that we are as real as you are; you must accept that you are not God."

"We can't choose our fate, but we can choose others. Be careful in knowing that."

"Besides, the world isn't split into good people and Death Eaters. We've all got both light and dark inside us. What matters is the part we choose to act on. That's who we really are."

"Dumbledore will only leave from Hogwarts when there are none loyal to him!"

"There are some things you can't share without ending up liking each other, and knocking out a twelve-foot mountain troll is one of them."

"Understanding is the first step to acceptance, and only with acceptance can there be recovery."

"It 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."

"The thing about growing up with Fred and George," said Ginny thoughtfully, "is that you sort of start thinking anything's possible if you've got enough nerve."

"Is 'fat' really the worst thing a human being can be? Is 'fat' worse than 'vindictive', 'jealous', 'shallow', 'vain', 'boring' or 'cruel'? Not to me."

"To the well-organized mind, death is but the next great adventure."

"You might never fail on the scale I did, but some failure in life is inevitable. It is impossible to live without failing at something, unless you live so cautiously that you might as well not have lived at all - in which case, you fail by default."
