I moved to a role supporting a team that had been told that huge numbers of things were "impossible" by a brilliant guy given to migraines. If you asked him on a good day, he could do anything. But on a bad day he just wanted you out of his office. By his demonstrated competence, they took what he said as gospel. I spent an hour or two a week dragging "impossible" things out of them and fixing them. They were very happy and ascribed wizard-level powers to me.
