Examples are often cited of Napoleon quarreling and coming to blows with other children almost every day, of living in relative isolation, and making very few friends. Stories are told about his days at Brienne that reinforce the image of a willful loner: Napoleon finding solace and refuge in a garden he cultivated with the greatest care, around which he had erected a palisade, where he spent his time reading or dreaming, and reacting violently when that territory was accidentally transgressed; Napoleon refusing to bend to the will of a monk who wanted to punish him by making him kneel at the door of the refectory - he ended up having a fit and vomiting; Napoleon leading a group of boys to victory in a snow fight; Napoleon egging on his fellow students to throw their mattresses out of a window to provoke a monk.
In his youth we can read that Bonaparte was somber and even shy. Constantly alone he was the enemy of every game and every amusement … he seemed to know that destiny would call upon him one day … it was as though he was practicing in advance for a role he was to play.
Cold reserved, taciturn, almost always alone replying only in monosyllables, for a long time he retained the nickname of Spatiate. For a long time he was without any trustworthy friend: he studied a student for a long time before forming the slightest liaison with him; he appeared to be looking in his fellow schoolmates for a soul of his own caliber.
Dwyer on Napoleon’s childhood. Interesting to note that he resembled an INTJ for a substantial part of his youth before becoming the infamous ENTJ he is currently known as.
