The proposed Adversity Quotient is supposed to be a measure of how resilient one is in the face of challenges. However, one could also interpret it (from the book's examples) as how indifferent a person is. In this perspective, it is difficult to appreciate the usefulness of the idea.

I took a course from the author in which we used this book along with other materials to understand our own abilities when dealing with adversity and best practices when under stress. I found the concept of the AQ fascinating and have continued to find the things I learned very useful years after.
