Whatever house I'm in, I hope she's not in it.

I've never managed to keep a journal longer than two weeks.

The mind is not a book, to be opened at will and examined at leisure. Thoughts are not etched on the inside of skulls, to be perused by an invader. The mind is a complex and many-layered thing.

I think the single biggest thing that money gave me-and obviously I came from a place where I was a single mother and it really was hand to mouth at one point. It was literally as poor as you can get in Britain without being homeless at one point. If you've ever been there you will never, ever take for granted that you don't need to worry. Never.

In truth, I never consider the audience for whom I'm writing. I just write what I want to write.

You have to be free to fail in this world.

The Potter books in general are a prolonged argument for tolerance, a prolonged plea for an end to bigotry. And I think it's one of the reasons that some people don't like the books, but I think that's it's a very healthy message to pass on to younger people that you should question authority and you should not assume that the establishment or the press tells you all of the truth.
