The defining characteristics of the Type A Behavior Pattern (TABP) are a strong drive to succeed, hostility, competitiveness, perfectionism, a desire for recognition, wealth and advancement, difficulty talking about feelings, and a sense of urgency and impatience.Your interactions with others, while generally characterized by warmth and tolerance, are also at times tinged with impatience and hostility. When you’re stressed or frustrated, you can lash out at others or end up stewing in anger or frustration."
