This book holds a special place in my heart because it was my first introduction to cognitive psychology. I found the book and bought it as a young teen, not even knowing what psychology was or that I'd one day major in it and learn far beyond what's in this thin little volume. That said, this book is still extremely relevant today, even though cognitive behavioral therapies and theories have changed, and new skills in DBT and ACT have been developed.
The late Dr. Albert Ellis is a very logical, readable, refreshingly honest master. Ok, onto the book.
The book is a practical and helpful look at REBT - rational-emotive behavior therapy. Ellis and Becker introduce the ABCs of rational thinking and guide readers through the process of combating shyness, guilt, sex shame, relationship issues, work challenges, and more. Essentially when something happens (A), we evaluate it (B), and, based on that judgment, we (C) actuate - produce an emotion or behavior. These evaluations in the (B) step are often irrational (based on faulty thinking). Irrational thinking is generally black and white and includes the word "must" - "I must..." or "You must..." Because we tend to hold perfectionistic, inflexible expectations, we damn our person instead of simply evaluating our behavior and making adjustments. There are many good, relevant examples in here from no-nonsense but brilliant thinkers.
