Introverted: The introverted person would be a quiet, reserved individual who directs his or her own interests toward self rather than others.  One who would generally keep to him or herself and not make many, if any, overt gestures to meet new people on their own, probably seeking and introduction from a mutual friend or acquaintance.  This individual would probably not be a risk taker, especially in social situations and would not be very comfortable, for example, making "cold calls" in sales.
