Delivering Happiness: A Path to Profits, Passion, and Purpose (2010) is a book by Zappos CEO Tony Hsieh.

[1] He wrote most of the book stream of consciousness, often completing 3,000-word chunks a day that he would send to his editor in New York City.

The second section, Profits and Passion, details Hsieh's involvement with Zappos, beginning with joining the company full-time as CEO in 2000.

[11][12] It also spent nine weeks in the USA Today Besteller list, where it peaked at 9, and was one of the Top 10 Amazon Bestsellers for June and July.

[13][14][15] At least part of the commercial success of Delivering Happiness can be attributed to ResultSource, who undertake best-seller campaigns on behalf of authors, meaning they purchase books in bulk to game The New York Times bestseller list and others.
