Tony Hsieh is a really nice guy. This is what makes him a very unusual CEO, which is what makes his company so interesting. It also makes him a writer who doesn't use much corporate lingo, and a terrifically casual reader of his own book on the growth and development of Zappos, his unique company. One part memoir, one part philosophy, one part corporate handbook, and all silly optimism, Delivering Happiness will appeal to a surprisingly wide audience.

Hsieh begins with his business history, which adequately conveys his wackiness. First, there was the worm farm in elementary school. All the worms escaped, and he lost money. Then there was the mail order button business in middle school, so successful that he passed it along to his younger brothers in succession. In high school, he learned a bunch about programming, thereby combining his instincts with an appropriate knowledge base. He laughs out loud at his own computer club lunchtime antics, and so will you. Then there was the pizza business in his dorm at Harvard, where Hsieh found innovative ways not to attend any classes, and a high-paying corporate gig after graduation where he once again did as little as possible.

This is a man who likes to take business risks, and as he explains how he made decisions that caused him to grow from slacker into a Red Bull-pounding, 24-hour working machine, you'll be amazed that it sounds like he's smiling the entire time. From his first major start-up, which was subsequently sold to Microsoft, to his repeated close calls where Zappos almost went under before it was eventually bought out by Amazon, this true story of one man's corporate odyssey will leave you believing that anything really is possible. It will also at least make you want to shop at Zappos, if it doesn't make you want to move to as Vegas to work there.

Shot through with brief guest-narrations using the actual participants relevant to Hsieh's fast-paced world of entrepreneurship, there are a wealth of memos, emails, and testimonials that all serve as evidence to his weird intellect. And if you played a drinking game where you drank a shot every time Hsieh mentions having a drink, you'd be drunk before the book is half finished. From the tone of his voice to the story he tells, this is clearly a guy who needs his work to be fun and challenging. Just as Zappos has done, Hsieh's book casually fires the opening volley in a new era of corporate culture and management.

This eye-opening treatise on how to be happy at work has the added bonus of an hour-long conversation between Tony Hsieh and Warren Bennis, who has been universally considered one of the most significant leadership gurus for the past 40 years. Much of what Hsieh says is a more concise version of what he says in the book, though insights from the aging but still hilariously astute Bennis do offer something extra exciting. They discuss happiness in a way that is useful to all people, not just corporations. Megan Volpert
