Meditation teacher and writer Jeff Warren and our host Dan Harris reflect on their January 2017 road trip, in which they traveled from New York City to Los Angeles to talk with people about what keeps them from meditating, and in the process, the two friends discuss how meditation has helped them work through their own personal struggles. Their new book on their journey, written with Carlye Adler, is called "Meditation for Fidgety Skeptics: A 10% Happier How-to Book," which is on sale Dec. 26 and available for pre-order now.
