The people who I deal with in my daily life - at work, at church, and in my family - I found many of them in the pages of this book. None of them are ill enough to be unable to function in daily life, and yet, they are in some way impaired or they have failed to meet their potential. This book was a wonderful exploration of the complex biological and environmental factors that interplay to make each individual's personality. It gave me great insight into understanding how, once you accept your biology, it does not have to be your destiny. It shows how people can, if they so choose, work around their limitations. What a wonderful and powerful tool for everyone to have in their human dealings.
