NLP is a method of modelling. Modelling is a process of acquiring skill. However, modelling does not result in achieving the whole life experience of another person. People are not broken, they work perfectly. They do not need to be fixed.
People have all the resources necessary to make any change.
People make the best choices given their resources available to them. All external behaviour is the result of internal processes. The map is not the territory. Our perception of reality is not reality itself. We do not operate directly on our world, but rather through our perceptual map of the world.
