As your review of recent research by two psychologists argues, living abroad appears to give you a creative edge (“Expats at Work,” May 16, 2009). William Maddux of INSEAD, a business school in Fontainebleau, France, and Adam Galinsky of the Kellogg School of Management in Chicago have shown that merely traveling abroad is not enough. Living in foreign parts helps foster creativity presumably because one is continually confronted by novel experiences that keep one’s mind busy. By extension, returning to your own land after many years of living abroad is still fraught with the unexpected, and it thus promotes creativity once again. This is my own experience, as well as the experience of many returning expats among my friends. Returning to Croatia after more than half of my life in America and England has hardly changed my expat status. Once an expat, always an expat. And always fielding all manner of unexpected challenges.
