Studying a foreign language has its own momentum: The more you learn, the more you want to learn. Say you love Italian food and decide to study Italian. At first it's hard. But one day you meet some Italian tourists on the bus and you understand enough to point them toward their hotel. Before you part ways, they give you their e-mail address. Now you want to write to them -- so you study some more.
Do you enjoy learning a foreign language? Can you picture yourself teaching it to kids? If so, consider becoming a foreign language teacher.
