After 49 days fasting under the Bodhi tree, Siddhartha Guatama was struck by an idea. We suffer because we are attached to things, to people, to desires. When we can't have it, we feel an emptiness. But what if we never wanted it in the first place?

Guatama taught his philosophy for the next few decades, and centuries after that his followers would give him a new name – the Buddha. Total, complete elimination of your yearnings was called Nirvana.

In our networked world, where we broadcast on social media what we want others to see of us, Nirvana can seem far away. But our guest today says that the yearning to belong shapes our behaviors in ways we're not often conscious of.

Dr. Michael Gervais is host of the podcast Finding Mastery, where he pulls on his experience as a high-performance psychologist to draw out what makes these top athletes and board room professionals tick.

He's out with a new book – The First Rule of Mastery, Stop Worrying About What Other People Think Of You.
