QUOTE : Another kind of HSP could potentially have an even stronger pause-to-check system but an activation system that is also very strong—just not quite as strong. This kind of HSP would be both very curious and very cautious, bold yet anxious, easily bored yet easily overaroused. The optimal level of arousal is a narrow range. One could say there is a constant power struggle between the advisor and the impulsive, expansive warrior within the person.
