Balance. It was all about balance. That had been one of the first things that she had learned: the centre of the seesaw has neither up nor down, but upness and downness flow through it while it remains unmoved. You had to be the centre of the seesaw so the pain flowed through you, not into you. It was very hard. But she could do it!
Terry PratchettThe Library didn't only contain magical books, the ones which are chained to their shelves and are very dangerous. It also contained perfectly ordinary books, printed on commonplace paper in mundane ink. It would be a mistake to think that they weren't also dangerous, just because reading them didn't make fireworks go off in the sky. Reading them sometimes did the more dangeous trick of making fireworks go off in the privacy of the reader's brain.
Terry Pratchett(About sweeping).... What he was in FACT doing was moving the dirt around with a broom, to give it a change of scenery and a chance to make new friends.
