The Jan-Feb double-issue of Harvard Business Review has an excellent series of articles about happiness in business. I was pleasantly surprised when I grabbed it at the airport; getting an issue of HBR is one of my self-awarded travel perks, and I didn’t even look at the cover! From some countries move from GDP to Happiness as their prime measurement of economic accomplishment, to the very history of Happiness, this is a great collection of articles for those of you looking seeking a rational basis for fulfillment. Highly recommended.
