Narcissism

“Narcissistic personality disorder (NPD) is a personality disorder[1] in which a person is excessively preoccupied with personal adequacy, power, prestige and vanity. This condition affects one percent of the population.” - DSM-V

I think the percentage is higher among those of us who have been drawn to speak via broadcast transmitters.

Symptoms:

• Feel what they say is more important than the music and show it to listeners by talking over songs or telling the audience when they don’t like a particular tune.
• Drop scheduled songs.
• Bits go long. 
• Go to the GM if they disagree with the PD’s suggestions for programming
• Refuses to attend station events unless they get paid or are the center of attention

Changing these patterns requires a seldom-brief process of helping them become more empathetic in everyday relationships.

Interrupt their sense of entitlement and self-centeredness by guiding them to identify their unique talents.

Encourage them to help others for reasons other than their own personal gain.

If you can actually achieve this, you will have helped this individual in their life and relationships with everyone, not just their radio show.

That's the rare, amazing payoff you get for training yourself to be an effective leader.

It's worth the personal risk, time and effort.
