The funny thing about business books is that for many stories, there are countless counterexamples of management philosophies that are radically different, yet still successful.

CEO Tony Hsieh’s (pronounced “shay”) retelling of the Zappos story in the upcoming Delivering Happiness is a zippy, pleasant read about a business model that doesn’t compartmentalize labor and leisure.
