The theory describes a Type A individual as ambitious, aggressive, business-like, controlling, highly competitive, impatient, preoccupied with his or her status, time-conscious, and tightly-wound. People with Type A personalities are often high-achieving "workaholics" who multi-task, push themselves with deadlines, and hate both delays and ambivalence.
The theory describes Type B individuals as perfect contrast to those with Type A personalities. People with Type B personalities are generally patient, relaxed, easy-going, and at times lacking an overriding sense of urgency.
Because of these characteristics, Type B individuals are often described as apathetic and disengaged by individuals with Type A or other personality types.
