Fear is not the mind killer. Fear can sharpen our wits, heighten our perceptions, and induce much needed caution into a dangerous environment. Fear is a tool sharpened by billions of years of evolution, one that should not be lightly tossed aside. Panic, handmaiden to fear, is useless and counter-productive, but this essay is not about panic but the true mind killer.
Despair is the mind killer.
Where despair takes root initiative dies. The thoughts grow sluggish and foresight sees nothing but doom when the mind is wrapped in despair. Unlike fear that make you hyper-aware of the things and consequences, Despair robs you of perception and tell lies of the future. Despair will have you lay down your arms and surrender when the battle has not yet been joined. Taken with cynicism masquerading as wisdom despair is defeat preordained.
Reject despair, even when odds of hopeless and you see no path out, fight on, you can not know the future and life is full of strange and unpredictable twists.
