Many people use NLP as a form of self development. No one is wrong or broken. People work perfectly to accomplish what they are currently accomplishing. People already have all the resources they need. Behind every behavior is a positive intention.
Every behavior is useful in some context.
The meaning of a communication is the response you get. There is no such thing as failure. There is only feedback. In any system, the element with the most flexibility exerts the most influence. The map is not the territory.
