This image is making its way around facebook, and on first look, I can see why most people feel like it makes sense. But I have been doing a lot of personal work around fear lately, and I have a different perspective.
I think that fear is a good thing. At its core, fear is a set of physiological, psychological, and emotional responses to external threats. It evolved to basically save our lives in the face of lions, tigers and bears (oh, my!) It is, in a sense, a protective adaptation. If we didn't feel fear, and respond to it, we would be in danger of not being careful enough.
