Fear is a great controller. What is your biggest fear? Why is that a fear of yours? When did it become a fear? What can you do to overcome this fear? Have you even given it much thought? Fear is an emotion that we feel whenever we "believe" something is threatening, or dangerous. Although the thing that we fear could have happened decades ago, in the moment that we feel the emotion of fear, that emotion is the result of an emotional assessment of a situation or circumstance.
