Don't, Ginny, we'll send you loads of owls. We'll send you a Hogwarts toilet seat. George! Only joking, Mum.

I am very frustrated by fear of imagination, I don’t think that’s healthy.

I would be a liar if I said I don't care [about my appearance]; yes, I care. I found it very difficult, when I first became well known, to read criticism about how I look, how messy my hair was, and how generally unkempt I look. The nastiest thing ever written was written by a man, and I do remember that. I wasn't looking for it either, it was just simply in the newspaper I was reading.

Children's books aren't textbooks. Their primary purpose isn't supposed to be "Pick this up and it will teach you this." It's not how literature should be. You probably do learn something from every book you pick up, but it might be simply how to laugh.

Dumbledore had not raised his voice, he did not even sound angry, but Harry would have preferred him to yell; this cold disappointment was worse than anything.

Magic has universal appeal. I don't believe in magic in the way that I describe in my books, but I'd love it to be real.

I'm not a billionaire, what a tragedy.
