Even when he tried to be a good teammate, that was little naturalness or spontaneity. Self-preoccupied people hit the right notes, but often so hard that they sound tinny. Self-preoccupation creates an ego that is at once overinflated, insatiable and overly sensitive. Self-preoccupation also seems to make it hard for supremely talented people like A-Rod to deal with their own talents.
One of the mysteries around Rodriguez is why the most supremely talented baseball player on the planet would risk his career to allegedly take performance-enhancing drugs?
My theory would be that self-preoccupied people have trouble seeing that their natural abilities come from outside themselves and can only be developed when directed toward something else outside themselves. Enclosed in self, they come to believe that their talents come from self, are the self. They have no outside criteria that tells them what their talents are for or when they are sufficient. Locked in a cycle of insecurity and attempted self-validation, their talents are never enough, and they end up devouring what they have been given.
