I remember during 'soft skills week' on the grad scheme at a former employer several years ago we had an 'NLP trainer' come along and spend some time with us... it all seemed very dubious, the best part of that week was the two days we spent with professional actors going over presentation skills, posture, voice coaching etc... the NLP stuff was comically bad in comparison, the guy even claimed that this was what Derren Brown uses (he doesn't, he's a magician and he's been quite critical of NLP). I'd suggest reading up a bit about this field, it is basically pseudo science - sure some people swear by it but then again people swear by homeopathy and magic healing crystals too.
