"Those who pray for your downfall are concentrating negative thoughts towards you, without taking cognisance of the slippery ground in which they are standing, which could lead to their downfall."

Until I saw my drawings replayed on the iPad, I'd never seen myself draw. Someone watching me would be concentrating on the exact moment, but I'd always be thinking a little bit ahead. That's especially so in a drawing where you are limiting yourself, a line drawing for example. When you are doing them you are very tense, because you have to reduce everything to such simple terms.
