If you have a fear of something specific, your unconscious mind learned or adopted that fear in a single moment. Therefore, your fear can be unlearned or released in a single moment.

If you have a more generalized anxiety, it just means that you have a fear of several similar things. They may not seem similar, but to the unconscious mind, they represent the same threat. In this case, keith will first lead you through hypnosis to the key moment in your past where your mind decided these fears were important to have. Then the general fear becomes specific, and it can be released in a single moment.
