Positive stress can provide zest and enjoyment, as well as attentiveness and energy for meeting deadlines, entering new situations, coping with emergencies, achieving maximum performance and meeting new challenges. In moderate amounts, stress is useful. Even in large doses, it is often appropriate and vital.
Arousal is part of life.
The goal of stress management should be to control stress so it turns into harmful distress as infrequently and as briefly as possible.
