A teacher at Oklahoma City College trained a large number of Broadway musical performers. She was quite direct, as might a coach, showing each person how to do better by various particular moves and changes. She said, "If they can't take the criticism they came for--then don't come."
We all need encouragement, but even more we need coaching that points to how to become better. Such tough teachers are your blessing.
