This week we are fortunate to have Professor Steven Hayes. He developed one of the key mindfulness-based therapies in use today, called Acceptance and Commitment Therapy (ACT).

He's written over 30 books and published over 300 research papers, which is very impressive. Hayes is Nevada Foundation Professor at the Department of Psychology at the University of Nevada. His book, 'Get out of your Mind and into your Life' is a major bestseller and was featured in Time Magazine. When the book came out, it was the number 1 best-selling self-help book in the US.
