" he was doing what he was meant for—something so perfectly aligned with his nature that it was as easy as breathing. It made sense suddenly that you’d like it, that it would be everything you wanted to do, if there were something you were this good at, and it rewarded you with endless buckets of mana on top. Your own body would teach you to want it more than anything—want it so much you’d have to learn to want anything else. "
