I found the new version of Please Understand Me to be hard to read, written in a very academic language. What made this book very easy to understand was a companion title I purchased called Understanding Yourself and Others, An Introduction to Temperament, by Linda V. Berens, Ph.D.. This book simplified the ideas in Please Understand Me II, but did not lose the richness of the concepts. I recommend purchasing it with Please Understand Me II, it is only $4.95.
