"The first quality of a General-in-Chief is to have a cool head which receives exact impressions of things, which never gets heated, which never allows itself to be dazzled, or intoxicated, by good or bad news. The successive simultaneous sensations which he receives in the
constitution, paint mental pictures out of everything: however exalted be their reason, their will, their courage, and whatever good qualities they may possess, nature has not fitted them to command armies, nor to direct great operations of war." - Napoleon Bonaparte
