Headspace CEO Rich Pierson talks with Kara Swisher and Lauren Goode about meditation apps and why it's important to find stressed out people where they already are — on their phones. Pierson says people used to back away from him and his co-founder when they learned about the company, but the world is coming around to the idea of guided meditation as a valid way to improve one's mental wellness. He also explains why meditating can sometimes make you angrier or, at least, more aware of how angry you already were. Plus: Kara shares her own not-so-zen, and decidedly morbid, meditation regimen.
