Rethinking self-optimization

This episode is a bit different, and I am in the hot seat. Dan Harris (@danharris) interviewed me for his show, the 10% Happier with Dan Harris podcast, and I thought it was worth sharing here. Dan is a wonderful interviewer, and we got in the zone. He is also the bestselling author of 10% Happier and Meditation for Fidgety Skeptics: A 10% Happier How-To Book.
