We're able to understand another persons point of view and avoid arguments better, we're able to negotiate better and we can now see a clear focus of what we are trying to achieve in life and business and can identify the paths we need to take to achieve it. In these examples, NLP has absolutely worked and continues to work -- why, or how, or can we prove it? Can we verify how we moved our values, can we verify how we have changed a strategy or the process for removing a limiting belief... Who cares, so long as the practitioner is able to assist the client in getting results then that's all that really matters! NLP is more than just a series of techniques, it's an attitude of continual learning, creativity and of the use of mind's natural ability to do amazing things... whether it can be studied or not!
