Overconfidence and cowardness were two elements that were closely related, and a person could be at the same time overconfident and a coward.
Such a person would always believe that they could do anything, that they were always right, but that was only because they feared failure.

Nevertheless, such a person would meet a bitter end, sooner or later, as no one would be absolute while being ignorant.
