So NLP is short for neuro linguistic programming.. so you go for a session with a NLP practitioner and they use specific language to guide you through a session to clear negative belief patterns that you have sub consciously formed likely from incidents from when you are young - NLP has proven very successful with varying things from phobias, to weight loss, to breaking through into new income brackets etc
