If the Wikipedia entry on NLP (Neuro Linguistic Programming) is to be believed, it is all a bunch on mumbo jumbo. If that’s true, why then, have over 150,000 people in the UK been trained in it and report using it with success? Why do people like Pharrell Williams, Oprah Winfrey and Warren Buffet sing its praises? Why do a lot of counsellors and psychotherapists secretly use it without labelling it? Why is it so popular in the sports and business world?
