As a kid, I was so prone to seriousness that one teacher noted on my report card, “Excellent with fractions. Very serious.” As an adult, I’m still excellent with fractions; however, I’ve learned to balance my seriousness with not-so-serious experiences that bring levity, silliness and joy into my life. Traveling presents so many opportunities for happiness-inducing experiences. If I want to cater to my contemplative and introspective side, visiting the museums and historic sites in big European cities is the ticket. But to bring sheer glee into my travels, I seek out offbeat, unexpected celebrations and festivals. I find they’re a pure ode to joy, and I bet any one of these festivals around the world would make a most serious traveler burst into smiles.
