Of late I've come across some articles on the topic of what makes us happy. Tony Hsieh of Zappos has some great insights on this. Recently in Ode magazine, I read an article that referenced a study by two professors, from the University of Wisconsin and University of Chicago, that looked at the relationship between happiness and different kinds of consumption. In their research, only leisure ("money spent on vacations") and vehicle consumption correlated with happiness, and to our well being. No other type of consumption, including spending on food or health, did so. In case the subject interests you, it turns out there's even a Journal of Happiness Studies, founded by Ruut Veenhoven, a professor at Erasmus University in Rotterdam.
Likewise, research at the the universities of Rotterdam and Tilburg "found vacationers reported a higher degree of happiness...compared to non-vacationers." Indeed, we look forward to making our customers happy! I guess our luxury travel experts are in the happiness business!
