Neuro Linguistic Programming, founded by Richard Bandler and John Grinder is all about using language to change behaviour. By changing your language, you give yourself, permission to remove limiting beliefs and instil confidence.  I completed the NLP master practitioner course 15 years ago. It was life changing. The unique language system is utilised to reboot and reorganise behaviour patterns. The foundation of NLP is that we can fix or get rid of any unwanted behaviour by tapping into the unconscious mind.
