It seems a little hard to buy the idea of something as complex as happiness being simplified into a few letters and symbols. But whether or not I’m totally convinced, I’ve come to realize that there is a lot to learn from the research behind these formulas for happiness. It turns out that there is a whole field of research in this area, and there are a lot of experts out there that each have their own explanation for what makes us happy (or not). In fact, there’s not just one, but several formulas and equations out there that promise to explain happiness.
