10% Happier with Dan Harris Folgen

Arianna Huffington has a multimillion-dollar media website that reacts to world events by the millisecond, she's a mother of two -- and yet she says she always gets a good night's sleep. Not only that, she says wants to help everyone else do the same. Huffington, the co-founder and editor-in-chief of The Huffington Post, has a new book -- her fifteenth -- called "The Sleep Revolution: Transforming Your Life One Night at a Time." In the book, she traces sleep deprivation back to the Industrial Revolution and argues that our culture's chronic need to be "plugged in" is hurting our health, productivity, relationships and happiness. She started researching the effects of sleep deprivation after she collapsed from exhaustion in 2007, two years after launching The Huffington Post. It was also around this time, Huffington said, that she went back to meditation, a practice she had first started at age 13 while living in her home country of Greece.

Acclaimed movie producer and director Adam Shankman is best known for his upbeat, family-friendly movies, including "Hairspray," "A Walk to Remember" and "The Pacifier," but behind the scenes, Shankman says he spent years grappling with substance abuse and self-loathing. Growing up in Hollywood, Shankman, who is openly gay, remembers being "an incredibly happy kid." But when he was three years old, he says, his parents set him up with a doctor who was doing a study on sexual identity. Unbeknownst to his parents at the time, Shankman says he was placed in "conversion therapy." When he was a teen, Shankman turned to alcohol and later drugs to quiet the "ugly voice" in his head. In 2012, Shankman says, he entered a "really dark" place and the following year checked himself into a month-long rehab program -- where he discovered meditation.

Success and happiness: Can you have one without the other? Many may assume that these two things are at cross purposes but Emma Seppala, the science director of Stanford University's Center for Compassion and Altruism Research and Education, argues that that assumption is actually dead wrong. The Ph.D. holder and author of "The Happiness Track" sat down with Dan Harris to tackle this subject -- a central theme in Dan's own book, "10% Happier."
