This is what you are. You are intelligent. You are very inquisitive. You are a Narcissist. These are facts.
Narcissism is an adaptive mechanism.
Construct lists of self-punishments, negative feedback and negative reinforcements. Impose them upon yourself when you exhibit one of the behaviors in the first list. Make a list of prizes, little indulgences, positive feedbacks and positive reinforcements. Use them to reward yourself when you display a behavior of the second kind. Be objective, predictable and just in the administration of both punishments and awards, positive reinforcements and feedback and negative ones.
