Self-control is the good habit of a man who has mastered and controls his desires, impulses, emotions, and behaviors and uses reason and discipline to put holy choices into orderly practice so as to achieve some good outcome. The man with Self-Control is in command of his thoughts, impulses and emotions and uses both his reason and his will to consistently take right action to meet his goals.

Opposing Self-Control is the vice of Impulsiveness by which a man fails to regulate his emotions, desires and reactions to the world, and is ruled by his current whims and emotions, often causing himself and others suffering as the consequences of his flippant reactions bear bad fruit.
