Sleep is key to transforming your life, one night at a time. My guest is best-selling author Arianna Huffington, who joins me to talk about how to make great sleep a priority. Arianna had a major wake-up call herself when she collapsed because of sleep deprivation and broke her own cheekbone! As she looked further into the topic of sleep, she realized how modern-day life is built on a foundation of sleep deprivation -- and with some disturbing results. You don't want to miss my conversation with one of Forbes Magazine's 100 Most Powerful Women as she talks about how to give your own sleep habits a makeover. (She even taught me something new that's made a massive shift in my own sleep routine!)
