There was a real irony to the NLPers I knew who prided themselves on their communication skills yet because of their need to let everyone know how engaging they were, they were among the least engaging people I have ever known. In one extreme, we see this in the Christian fanatics who stand on the street and preach the word of their Lord, unaware that for every one rare, impressionable soul who might respond positively to their shouting and intrusion there are many hundreds of others in whom they have merely confirmed a belief that all Christians must be nutters. People are too often terrible advertisements for their own beliefs.
