“A cat has to be a monster to survive in this world.”

“There's no point in being grown up if you can't be childish sometimes.”

“Life is the first impression. We send it out before us, and it is there before we have a chance to make a better one.”

“The first step to any wizardry is naming something. To name a thing is to know it, and to know it is to have power over it.”

“A library is a place where you can lose your innocence without losing your virginity.”

“Any sufficiently advanced magic is indistinguishable from a rigged demonstration.”

“Power has its own personality, and it is a restless, curioso, and troublesome one.”

“Never accept the world as it appears to be. Dare to see it for what it could be.”

“There is no such thing as a small act of kindness. Every act creates a ripple with no logical end.”

“Heroes are made by the paths they choose, not the powers they are graced with.”

“Knowledge is a weapon. I intend to be formidably armed.”

“The first duty of a wizard is to help. The second is to learn. And the third is to not get killed.”

“Friendship is a weird thing. It's not something you can just decide to have. It's something that happens. And when it happens, you just know.”

“You can't go home again. But that's not true. You can go home again. It's just that home will have changed while you were gone.”

“To be a wizard is to be a servant, not a master.”

“The Universe is not a thing of black and white. It's all shades of gray.”
