The unconscious mind is awesome! It is completely and utterly dedicated to giving us what we ask for, protecting us and helping us be who we want to be... but sometimes we are unclear, or our conscious mind gets in a fluster giving the unconscious mind the wrond directions - for example "I get so nervous standing here talking to strangers..." suddenly knees are wobbly and palms are sweaty... the conscious mind reminded the unconscious mind that the person is normally so nervous...
NLP is used to help you learn to communicate effectively with unconscious mind and work with it to create the results you are looking for... and remove ingrained patterns that have been developed over years!
