With the publication of the 2001 text, Understanding NLP: Metaphors and Patterns of Change, Young assembled into a streamlined paradigm the collection of ideas about Neuro-Linguistic Programming that had evolved since the advent of NLP in the 1970s. This completely revised and renamed second edition reflects recent changes in the author's thinking about the different ways in which people perceive their reality and how they change. The ideas have been extended and refined throughout, creating a new edition designed specifically for those who wish to reexamine their existing knowledge of NLP and enhance their understanding of it. Young is a freelance writer, course designer, and trainer who has written for NLP magazines and presented at NLP conferences.
