Gretchen Rubin on the keys to adulthood and better living

In this edition of Entre Nous we speak to author Gretchen Rubin. Her latest book "Secrets of Adulthood" came out earlier this year. The number one New York Times bestselling author of "The Happiness Project" and "Better Than Before" also hosts the "Happier with Gretchen" podcast. We asked her about adulthood and how to make our adult lives that little bit easier.
