Johanna Siegmann has written a book called the Tao of Tango which is described as follows:

A modern allegory using Tango as the metaphor for life, The Tao of Tango is a journey of self-discovery. Based on lessons acquired from years of dancing Tango, The Tao of Tango provides you with a clear understanding of “opposites” and “balance”, detailed, step-by-step explanations of why we make the choices we make, and how to change the way we make those choices. By applying the extraordinary transformational elements I learned from dancing Tango to my own everyday life, I was able to make the profound, lasting changes I had begun to believe would never happen!

Sounds..interesting! :)
