Positiveness

“Positiveness of manner, and redoubtable inner conviction stem only from the mastery of superior knowledge, and this last is the fruit of application, preparation, thoroughness and the willingness to struggle to gain the desired end.”

The Armed Forces Officer Department of the Army Pamphlet 600-2

“Positiveness of expression suggests the superior's fixity of purpose, with consequent inspiration to subordinates to prosecute their tasks with determination.”

Sound Military Decision

“Positiveness is a good quality for preachers and orators, because he that would obtrude his thoughts and reasons upon a multitude, will convince others the more, as he appears convinced himself.”
