This is not the final word on courage, although it may be my final word that you will see published, for my medical prognosis is not what the doctor calls encouraging. Courage is not a veiled death wish as seen in the lifestyles that defy all reasonable expectations. Courage is not the instantaneous acts that most persons think of as heroic. Though many such acts are to be lauded, there is seldom much thought given to the consequences of one's actions.
Courage analyses all known factors then decides upon a course of action based on that analysis.
Yes, one may be fearful of the unknown. He may even be more fearful of known potentials. But courage acts even though harm may be to one's self. He that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart. He that backbiteth not with his tongue, nor doeth evil to his neighbour, nor taketh up a reproach against his neighbour.
