Personality may be set by preschool

Ever wonder if that quiet girl who hid in the back corner of the classroom ever burst out of her shell? Perhaps she became a whiz at computers. And what about the class clown? Did all his attention-grabbing antics develop into a charm that would later earn him big bucks selling timeshares in Bermuda?

New research shows that in most cases the personalities displayed very early in life — as young as preschool — will stay with us into adulthood. The wallflowers will stay shy and reticent, though they will learn in time to be a little more sociable and assertive. And the average kids, the more resilient ones, will remain so.
