Making the shift from self to service brings joy and also a deep sense of fulfillment to our jobs, relationships and the vision we create of our best life, says Oprah's friend Gary Zukav. He says this is the moment when we discover authentic power--“when your personality comes fully to serve the energy of its soul.” Fulfilling your purpose, with meaning, is what gives you that powerful spark of energy unique only to you, he says. In this episode of Super Soul Conversations Oprah sits down with such inspirational teachers, including Gary Zukav, Mastin Kipp, Paulo Coehlo, Sue Monk Kidd, Pastor Wintley Phipps, Nate Berkus, Diana Nyad, India.Arie, Janet Mock, Jack Canfield, Daniel Pink, Daniel Goleman, Shawn Achor, Jeff Weiner, Wes Moore, Shonda Rhimes and Devon Franklin to reveal how we can tap that source, which is our highest and truest version of ourselves. Interviews with these talented writers, speakers and thought leaders are excerpted from Oprah’s Emmy Award-winning show Super Soul Sunday. You can also find this compilation and other insightful conversations in Oprah’s best-selling book The Wisdom of Sundays.
