Now buckle on your armor. You do not need an intrepid courage, now;
intrepid courage may have brought you here; intrepid courage is but a
holiday kind of a virtue, to be seldom exercised, as experience will
teach you. You need firmness to resist all kinds of attacks. You need
good-nature, and yet you must repel temptation with a look as black as
Erebus. You need affability, yet you must speak almost by rote, and the
opportunities to keep from speaking outnumber the exigencies in which
you must speak by ten to one. You must be tender, and yet you must be
cruel as a surgeon. Without these opposites well balanced in your
character, you will not fight the battle successfully.
