“Silicon Valley has an insidious cult-of-personality problem. We idolize our most successful entrepreneurs, presuming that they're infallible, and we excuse and enable their worst tendencies, expecting only more and more success. Now, with detailed, revelatory reporting, Kirsten Grind and Katherine Sayre offer a much-needed reality check—a morality tale for our age. Happy At Any Cost is a startling portrait of one of our greatest tech visionaries, Zappos CEO Tony Hsieh—his celebrated innovations and his infectious capacity for joy; but also, behind the curtain, his wild excesses and addictions, his poignant mental-health struggles, and the coterie of enablers who hastened his decline.”—Robert Kolker, New York Times bestselling author of Hidden Valley Road and Lost Girls “Kirsten Grind and Katherine Sayre’s Happy at Any Cost presents a powerful and important case study of a leader overcome by mental health issues and addiction. Tony Hsieh’s story compels us to recognize: as the tech industry grows ever stronger, the eccentric genius founders it idolizes are vulnerable and human first.”—Sarah Frier, author of No Filter: The Inside Story of Instagram "Happy at Any Cost is a captivating story about one of the most innovative and complex entrepreneurs of our time, but it's also about the quixotic pursuit of happiness and the darkness many secretly battle."—Gregory Zuckerman, Wall Street Journal reporter and author of A Shot to Save the World “Happy at Any Cost is a beautiful, heart-breaking story that renders the late Zappos CEO Tony Hsieh in all his complex dimensions. On one level it’s a story exploring outside-the-box business aspirations, but there is a bigger lesson about the enormous, hidden burdens of people who pour all they have into their work and creative vision. I was sad to read Tony’s life story, but very glad to know it.”—Bradley Hope, co-author of the New York Times bestseller Billion Dollar Whale and Blood and Oil "Grind and Sayre’s volume focuses on a flawed man struggling to make happiness part of his business and his life....Beyond their discussion of Hsieh’s tragic death and legacy, Grind and Sayre also provide insight on the larger issue of mental illness and addiction hidden under Silicon Valley’s sunny surface."—Library Journal "[A] gripping cautionary tale....an eye-opening look at the dark side of success."—Publishers Weekly
