I model of designing offers a useful framework for understanding and managing emotions in order to assure a balanced, healthy and effective life.
All emotions are inherently surprising as they begin before rational thought can come into play.
Positive emotions tend to be learned and quickly mediated by conscious thought while negative ones tend to be characterized by immediate primitive responses to unanticipated experiences. Emotions range from immediate possessions through transient moods to more durable temperaments, habits and pathologies. They both motivate and guide thought and action. Different emotions, however, relate to different aspects of the model. Happiness fosters an increase in available energy and affords a readiness and enthusiasm for the task at hand and for striving toward goals through feelings of optimism, joyousness and brio.
