ESTP personality types always have an impact on their immediate surroundings - the best way to spot them at a party is to look for the whirling eddy of people flitting about them as they move from group to group. Laughing and entertaining with a blunt and earthy humor, ESTP personalities love to be the center of attention. If an audience member is asked to come on stage, ESTPs volunteer - or volunteer a shy friend.
Theory, abstract concepts and plodding discussions about global issues and their implications don't keep ESTPs interested for long. ESTPs keep their conversation energetic, with a good dose of intelligence, but they like to talk about what is - or better yet, to just go out and do it. ESTPs leap before they look, fixing their mistakes as they go, rather than sitting idle, preparing contingencies and escape clauses.
