This document provides a quick introduction to neuro-linguistic programming (NLP). It explains that NLP focuses on modifying and relearning behavior patterns through language and how the mind works. It discusses how the brain takes in too much information through the five senses, so it distorts, generalizes, and deletes information to form an internal representation. The document encourages noticing what information one distorts, generalizes, and deletes. It also explains that we can control our mental states like happiness and fear to manage stress, and that changing one's physiology through posture can impact behavior. With repetition, one can train their brain to develop new behaviors or get rid of bad habits.
