The visionary CEO of Zappos explains how an emphasis on corporate culture can lead to unprecedented success.

Pay new employees $2000 to quit. Make customer service the entire company, not just a department. Focus on company culture as the #1 priority. Apply research from the science of happiness to running a business. Help employees grow both personally and professionally. Seek to change the world. Oh, and make money too.

Sound crazy? It's all standard operating procedure at Zappos.com, the online retailer that's doing over $1 billion in gross merchandise sales every year.

In 1999, Tony Hsieh (pronounced Shay) sold LinkExchange, the company he co-founded, to Microsoft for $265 million. He then joined Zappos as an adviser and investor, and eventually became CEO.

In 2009, Zappos was listed as one of Fortune magazine's top 25 companies to work for, and was acquired by Amazon later that year in a deal valued at over $1.2 billion on the day of closing.

In his first book, Tony shares the different business lessons he learned in life, from a lemonade stand and pizza business through LinkExchange, Zappos, and more. Ultimately, he shows how using happiness as a framework can produce profits, passion, and purpose both in business and in life.
