For most skills, some people attain a level of art which surpasses describable taskification. If you asked a professional athlete how he throws the ball, or how he runs, he might mention a few tricks, but he's not going to be able to communicate it to you; in his mind, he just does it

Except that the level of art I (and I think Hugh) am talking about guidance for, is more analogous to learning the rules of the game than doing some part of it very well. And teaching someone the rules of a game is generally not regarded as difficult.
