It sparked my imagination. InterFuture sent me a letter (yes, I'm that old) that didn't talk about how much fun I'd have and show pictures of young Americans on beaches or in front of landmarks.
Instead, the letter laid out that I could design my own research project and carry out independently in two of twenty countries around the world. That was the thing I wanted - to go off exploring questions I had that went way beyond the classroom. I wanted to create something by pushing myself to new experiences.
