Neuro Linguistic Programming (NLP) is a psychological technique designed to improve behavior and enhance various aspects of life by altering mental patterns through language and neurological processes. Developed by John Grinder and Richard Bandler, NLP employs sensory modalities to help individuals recognize their strengths and weaknesses, allowing for personal growth and better reactions to situations. It serves as a tool for self-improvement and can influence both personal mindset and interpersonal interactions.
