The key to happiness? Know thyself, says Gretchen Rubin

What is happiness? How do you define it? Maybe it's feeling good, having a sunny disposition or being fulfilled, even if you don't feel pleasant all the time. Gretchen Rubin, host of the Happier podcast and author of The Happiness Project, says happiness is less about attaining joy than it is about growing in the right direction. In this episode, she explains how to make small changes that can move you toward happiness, and why knowing yourself helps contribute to this emotion.
