Everybody knows a performer when they see one: performers are loud and outgoing, friendly and confident. They reach right out to you and draw you into their world, promising a good time with someone who makes you feel totally at ease. I’ve never done a poll, but I’d suspect that the ideal performer to most of us is somebody that fits the rough definition Carl Jung laid out in the 1920s of an extrovert: a person who is sociable, takes charge, is outgoing, and is at their best in a crowd of people.
