Arianna Huffington's book, "Thrive," which advocates for a redefinition of success that goes beyond the traditional metrics of money and power. Huffington argues that we need a "Third Metric" which emphasizes well-being, wisdom, wonder, and giving. This new approach to success involves prioritizing sleep, disconnecting from technology, cultivating mindfulness, and embracing a life of service to others. By embracing these principles, Huffington believes that we can find greater happiness, fulfillment, and purpose in our lives.
