#13: Dr. Kevin Majeres and Sharif Younes discuss the different roles of the two hemispheres of the brain ("left brain" and "right brain"). Psychiatrist Iain McGilchrist re-popularized this paradigm in his 2009 book The Master and His Emissary, grounding it in neuroscience and using it to explain aspects of psychology, society, and culture (in contrast to previous pseudo-scientific versions of the theory). The approach has profound implications for understanding how to work at your best — with creativity and motives of service.
