The book I was reading is called Whole Brain Thinking. Working from Both sides of the Brain to Achieve Peak Job Performance (phew!) by Jacquelyn Wonder and Priscilla Donovan. William Morrow and Company, Inc. New York 1984. It's a little out of date (over twenty years old), but it's an interesting read anyway. I got this book from a book fair. Fill a bag for 15 bucks. I love to read and I got to the point that this was the only unread book in the house. (I'm only slightly addicted...) As it turns out, it's pretty good, but I'm only on chapter eight out of fifteen.
