Fear confines you. The steely wall of mental confinement extinguishes the fire of possibilities, exploration and discovery. It turns your aspirations into distant dreams. Fear constrains ambition, saps strength and draws you into the inner recess of the nothingness.
Fear is primal, perhaps the very pre-requisite of life. Without this complex neural mechanism, the species would have marched themselves to premature death, ending procreation and the world of living as we know today. Our brains learn fear and create responses to fear through the primitive neural engines involving Amygdala and Hypothalamus.
In controlled doses, fear commands alertness and action. Too much of it, you become inert. Fearlessness is not the absence of fear, it is the mastery and control of fear. The greatest advancements in science, exploration, sports and business is arrived by overcoming the rabid fear of failure. Shield the mind from spasms arising from the worst thoughts and terrible consequences. Unafraid march forward, push your limits, reach your horizons and conquer your true destiny.
