Joining the Harry Potter mania (or should I say hype? - don't get me wrong I love the books and movies), here are four quotes from the books' author, J.K. Rowling:

"It does not do to dwell on dreams and forget to live."

"It takes a great deal of courage to stand up to your enemies, but even more to stand up to your friends."

"To the well organized mind, death is but the next great adventure."

"Expecto Patronum!"
