What’s really behind the issues regarding self-esteem that seem to plague every woman, everywhere? 

This topic and many of its facets are discussed in Massaging the Female Mind. 
The book’s insights were gathered over the last 15 years in the emotionally healing environment of a massage room. 

The main principle is universal to all women: That the female ego does exactly the opposite of its male counterpart. A male's ego, left unchecked, will naturally overinflate his self-worth; while a female's, will organically destroy it. 
Why and how this occurs is just part of the book. Ways to counteract and even draw strength from this phenomenon are explained in-depth. Even though this book was written for women, ways of understanding men are contained inside. This is made possible because Massaging the Female Mind is written uniquely from the perspective of a male massage therapist.
