My first book with Ronnie was the result of extraordinary collaborative work between us. The book is more than a decade old, yet the idea of Four Worlds is hugely relevant, and we still have enthusiastic readers writing to us. The idea is simple: the four directions of the earth are more than just geographical locations: they provide us with a dynamic framework for transforming both ourselves and our organizations.
