This out-of-print book is the best of self-help books, making transactional analysis accessible to the lay reader. Because of the TA jargon, many people missed it's wonderful explanations of how and why we behave in the ways we do, and how to change. TA offers a wellness model, not an illness model, and Amy Bjork Harris outlines for us HOW to use the underlying principles of it to effect immediate changes and live an "I'm OK You're OK" life. There is no need for anyone to be remain "stuck" or in bad relationships with this book as a guide for his or her life! I'm torn between buying every used copy available to give for gifts, and leaving some for others to serendipitously discover this jewel!.
