Sometimes change can be achieved incredibly quickly. Take phobias for example. Neuro-linguistic programming (NLP) can be used to effectively and permanently remove many types of phobia in a single session. Whether it's snakes, planes (or snakes on planes!), spiders, high places or even the mother-in-law, the chances are that NLP can change the way you react to that old fear stimulus so that you literally cannot think of it in the same way again.
