"Fear is the most debilitating of emotions because it shrinks from confrontation with its object. This withdrawal lends itself to the formulation of fantasies which are difficult to disengage from. In its inability to confront reality, fear is the source of all chronic feelings of inadequacy and inner emptiness.
The main problem with fear is that it is self-reinforcing. When we act upon the basis of fear, the fear increases." - The Mind of the Markets, by F. J. Chu.
