They see Hermione as someone who is not vulnerable, but I see her as someone who does have quite a lot of vulnerability in her personality.
J. K. RowlingFailure meant a stripping away of the inessential. I stopped pretending to myself that I was anything other than what I was, and began to direct all my energy to finishing the only work that mattered to me. Had I really succeeded at anything else, I might never have found the determination to succeed in the one area where I truly belonged. I was set free, because my greatest fear had been realized, and I was still alive, and I still had a daughter whom I adored, and I had an old typewriter, and a big idea. And so rock bottom became a solid foundation on which I rebuilt my life.
