As the world largely knows by now, there are many great things about Zappos. But what most people don’t realize is the extent to which that quest for greatness permeates their DNA. Some C-level folks talk a good game about customer and employee happiness, but Tony Hsieh (CEO) can credibly say that he’s obsessed with it. When I partnered with Zappos to graphically record their Culture and Key Books class, I couldn’t help but be impressed by the quality of the conversations and the commitment to what I would almost refer to as ‘employee enlightment.’  And Tony is personally studying the science of happiness – a subject that emerges throughout the PowerPoint we’re working on – not only to pursue his own bliss but also to create joy and good experiences for his staff and customers. It’s a rare sight to behold a humble, intelligent and driven CEO who also takes time to create warm fuzzies. Good for him. And in my book, it doesn’t hurt his case for personal greatness when he’s willing to stand in front of my logo so I can take his picture.
