Randy Haveson, MA, developed the foundational concepts featured throughout “Worth at Work,” including the ego versus self-esteem continuum, the “bully voice” versus “best friend voice,” the energy ball, and the four dimensions of self. These frameworks emerged through his personal journey of transformation and decades of helping others build self-esteem and confidence. He first introduced many of these concepts in his previous book, “Becoming Your Own BFF.”
