"Delivering Happiness" by Tony Hsieh

Hsieh, the CEO of Zappos, has gained a reputation for being forward-thinking with his approach to hiring employees and running his online shoe store.

In "Delivering Happiness," he meditates on some of the more successful policies he's put into place, and discusses the psychological research that underpins much of what he does. New employees, for instance, are offered $2,000 to quit on the spot — a clever technique to weed out people who don't want to be there.

Zappos may sell shoes, but Hsieh emphasizes the principles apply no matter what you put up for sale.
