NLP (Neuro-linguistic Programming) is an approach to communications, change, and performance that considers both the conscious and unconscious mind. It defines states as the combination of thoughts, emotions, and physical energy that determine one's mood. States can be either resourceful or unresourceful. People create their states based on how they perceive the world through their five senses, but this perception is altered by processes of deletion, distortion, and generalization of information before it reaches the conscious mind.
