The idea of currency, of money, always fascinated me. I remember collecting foreign coins as a child. I was excited when my grandparents brought me back Lira after a trip to Italy. One of the most exciting aspects of a childhood trip to Niagara Falls was paying with Canadian dollars. Money is a weird concept if you think about it. Something that is only worth anything because everyone tacitly agrees on it. As a student of business and economics, I think money and currency are some of the most interesting aspects of the field. For people like me, the euro experiment was very interesting. It is very unsettling to have one currency replace another. It changes your perception. Suddenly you pay more attention to the price of things and notice changes in price. It feels like you are spending foreign money. More than the transition to the euro, it took a long time for me to stop thinking in US dollars and switch to calculating in euros in my head. Only after years of earning in euros did I start thinking in Euros.
