"Abuses of any kind (verbal, emotional and physical) can definitely take their toll on one's confidence, concentration and motivation levels, not to mention self-esteem. In sports, people in power sometimes rationalize bullying behaviors by saying that they are trying to build "mental toughness" in their players. But no one ever gets good by being told they are bad or by being treated poorly.”
