Oprah Winfrey and Arthur Brooks want you to be happier - so the TV megastar and the Harvard academic teamed up to write a book setting out the steps you can take to be a little happier each day. 

Over the summer, Dr Laurie Santos read Build the Life You Want, the Art and Science of Getting Happier and loved it. So she recorded a conversation with Arthur touching on how his son found meaning in the marine corps; why you should remove the all mirrors from your home; and whether happiness experts can ever be happy themselves.
