The main NLP idea is that regardless of what happened to you in the past, you can live a normal life, not affected by any past event.
This can happen only when we disrupt the subconscious mechanism by which you were “re-bring” the past event into your now- on a purely subconscious level.
Saying NO can be the most challenging thing to do. The fear underlying this difficulty is fear of rejection.
Typically we are scared of offending someone, or we fear them getting angry. We are paralyzed by our fear, and keep on saying yes when we deeply feel we should be saying NO. As a result we compromise our own well being, and become hypocritical.
