“I think writing about the time in Hermione’s life that I write about – growing from childhood into womanhood, literally, I think it brought back to me how very difficult it is.So much is expected of you as you become a woman, and often you are asked to sacrifice parts of you in becoming a girl, I would say. Hermione doesn’t.”

“Don’t let yourself be. Find something new to try, something to change. Count how often it succeeds and how often it doesn’t. Write about it. Ask a patient or a colleague what they think about it. See if you can keep the conversation going.”

“A lot of teenagers write to me and say "I want to write a book. I want to get published." And those are two very different things. For the first one, that you want to write a book, I think is an excellent idea and you should totally do that because teenagers who want to write, you should be writing. You should be writing all the time like a maniac. Don't worry about the second bit, just yet because A. You need a lot of practice. You need to do it for, I'm not kidding, years. And then once you are published, it's a business. It's a job. Plus, every author I know was that teenager who sat in their room and read and wrote. That's who becomes an author, but that's what you have to do for a while before you become an author.”

“The funny thing about having any kind of moustache or beard is it grows on you—in two ways. I mean, it grows on you. It also becomes part of your identity. I've had it for 40 years. I don't think I would recognize the person in the mirror without it.”

“Darling,You asked me to write you a letter, so I am writing you a letter. I do not know why I am writing you this letter, or what this letter is supposed to be about, but I am writing it nonetheless, because I love you very much and trust that you have some good purpose for having me write this letter. I hope that one day you will have the experience of doing something you do not understand for someone you love.Your father”
