Dan Harris is a fidgety, skeptical ABC newsman who had a panic attack live on Good Morning America, which led him to something he always thought was ridiculous: meditation. He wrote the bestselling book, "10% Happier," and now Dan’s 10% Happier How-To Book has enjoyed a month on the New York Times Bestseller list. Spiegel & Grau published the hardcover on December 26, 2017.
