I don’t think that’s a question I can meaningfully answer. I think each person has more confidence and courage in some dimensions of life than in others. A given observer tends to see the person who is the most confident in the areas in which that observer is least confident and think of that person as the most confident — when that person might be quite lacking in confidence in areas to which the observer isn’t being attentive.
It was eye opening to read about Audie Murphy, a man who won the Congressional Medal of Honor for single-handedly taking on a unit of Nazis, a man who had a successful career in film, but also a man who was said to have been tremendously shy and awkward around strangers. It would be all in the context in which one saw Murphy that might make one think he was the most or least confident person around.
Quite frankly, the person who appears the most confident in all aspects of life is probably also the most full of shit.
