“I know I’m slapdash,” he was saying. “But there’s no need for you to copy me.  Always read right through, carefully first.  The shape of it should tell you a lot, weather it’s self-fulfilling, or self-discovering, or simply an incantation, or mixed action and speech.  When you’ve decided that, go through again and decide which bits mean what they say which bits are put as a puzzle.  You’ll find every spell of power has at least one deliberate mistake or mystery in it to prevent accidents.  You have to spot those.  Now take this spell…” Wizard Howl. ‘Howls Moving Castle‘  Diana Wyne Jones
