My glasses are the first thing I put on in the morning and the last thing I take off at night. This framed perspective of the world limits my view only visually, however; I hope.
When I spent a semester in Paris, I promised myself that I would eat anything. That vastly expanded my willingness to try new things, not just food.
I love to speak French, and I also have fun failing miserably to speak Spanish. I find it a point of pride that no one in Paris asked me if I am American.
The challenge of detangling the intricacies of the transport systems of the cities I visit is an oddity that I share with few people, but I can fascinate myself with maps for hours.
