This is old (20 years) and not a popular book. It's written by a psychologist and lacks the usual appeal you get from mainstream authors. However the content is solid.
The book talks about our core psychological desires. Unlike many personality profiling tools, this one is actually useful. The book also discusses how it compares to other research and what it means in daily life.
If the model holds strong, it's a game changer as it can be used to predict people's choices in the future. Think of choosing your life-time partner based on core desires and predicting possible friction in the future.
I'd recommend this book to everyone. It helped me to better understand myself and I think it will help you too.
