More personality....

The book is based on Carl Jung's Personality Type System and more research by Katharine Briggs and Isabel Briggs Myers....You can google "Briggs and Myers" and get a lot more info...The book is great because it applies it to children....

"Personality Type is a system for understanding the very different operating styles people have"...Nurture by Nature

Be gentle with the feeling/perceiving ones! They are sweet!
