Okay, so you'll have to file this one under "future weekend reading" because this book isn't out yet, but I thought I would provide a bit of a heads-up post in anticipation of what should be a very interesting read. Delivering Happiness: A Path to Profits, Passion, and Purpose is written by Tony Hsieh (pronounced "Shay"), CEO of online shoe retailer Zappos, and lands in bookstores in early June. Hsieh helped to create one of the most successful online retailers which was well known for its stellar customer service and which eventually was acquired by Amazon.

Hsieh's methods at Zappos turned convential wisdom on its head and helped land the company on Fortune Magazine's list of the best companies to work for in 2009 just before its billion dollar acquisition. Before Zappos, Hsieh was responsible for co-founding LinkExchange which sold to Microsoft for $265 million, and now for his third venture, Hsieh is authoring a book to share his experiences and methodology.

"I wanted to write a book to talk about the journey that I took in life in terms of what would bring myself long-term happiness, and what I accidentally discovered is that you can actually take concepts from happiness and apply it to businesses," says Hsieh in a video promo for his book. "Part of the goal of the book is letting people know that there is another way you can make yourself happy, make employees happy, make customers happy and still make money."

Hsieh recently pimped his upcoming book at SXSW with a promotional bus and managed to run into Leo Laporte's live stream parade to chat about his book. He also snagged a few moments from the eternally busy Robert Scoble to talk about about personal and professional happiness. The tech world is buzzing about Hsieh's upcoming book, as Kevin Rose, Tim Ferriss and even Aston Kutcher have been looking over pre-release copies.

For more information about the book and its author Tony Hsieh, check out the book's homepage and be sure to check back here for a review in June when the book goes on sale.
