NLP - Neuro-linguistic Programming

I read an article in the AAT magazine (the link is here but only works for me due to copyright).

Main points seemed to be it could be used for the following:

• 'Anchoring' to positive feelings eg associate sinple repeatable gestures with positive feelings to help a salesman remember success before going into a negotiation to give more confidence
• Being aware that feelings are linked to actions so watch body language to help understand what people are feeling
