What's left once you remove all the therapy stuff that has been mixed and confused with what NLP is?
Three things only.
First, the distinct modeling methodology NLP pioneered, which formalizes human beings' natural approach to learning.
Two, the Meta Model, which allows the Practitioner to effectively investigate connections between thought, language and behavior.
And third, the NLP alphabet, which allows the Practitioner to code the cognitive and behavioral patterns identified in modeling.
Everything else is just a distraction. Focus on what matters.
(And if you are in the United States, what matters today is giving thanks. Happy Thanksgiving to all my United States friends!)
