NLP is a way of understanding yourself. Why you act and react in a specific way and also a way of understanding ours.
It helps you to communicate with other and establish a positive rapport.
Richard Blander one of the developers of Neuro-Linguistic Programming was quote saying “NLP is an attitude and methodology than leaves behind a trail of techniques.
Every person has a different model of the world, so the key to a good relationship is to understand and to connect to other’s people model of the world. If not that you will be doing only what others believe but you will learn how and why they think the way they do.
