The world doesn't need another self-help book. As James Hillman said, "We've Had 100 Years of Psychotherapy and the World's Getting Worse." 

Almost all the problems you have that are worth solving are caused by your mind, and very few self-help books show you how to manage your mind.

Fortunately, there’s a new science of understanding the mind. It’s called Relational Frame Theory, and this book explains how you can use it to make your mind work for you instead of against you.
