Huffington says that while we tend to think of success along two metrics — money and power — we need to add a third.
"To live the lives we truly want and deserve, and not just the lives we settle for, we need a Third Metric," she says, "a third measure of success that goes beyond the two metrics of money and power, and consists of four pillars: well-being, wisdom, wonder, and giving."
Together, those factors help you to take care of your psychological life and truly be successful, or as the title of her new book suggests, "Thrive."
