Once in a Lifetime
Many of the lessons you will learn will be outside the classroom. Living on the economy in a foreign country will keep you on your toes. You will learn new customs, how to barter, stay safe, budget and become more flexible with people. There is no better way to learn a language than by immersing yourself in it. At first, it will be the toughest thing you have ever done. Eventually, it will become second nature.
You will become a more balanced person. New situations and challenges, from buying bread to traveling across town, will pop up daily. You will handle it and you'll do it by yourself. Before long, you will be ready for anything. Life in any part of the world will no longer surprise you. In your future career, this will be a benefit. International study on your resume will speak to your adaptability.
Moreover, you'll have contacts for life. When your employer wants to reach out and do business abroad, you just might be the person to lead the movement. If you want to bring your new family on a vacation back to where you spent your college days, you will have people on the inside.
Being able to step out of the United States and look back gives you a better perspective. How do other nations perceive us? What is it like to live in a different social system? What do you miss about home? What hang-ups do Americans have that other people find unnecessary? You might find that the “Land of the Free" has a great number of restrictions, like wearing bikini tops or not drinking beer on the train, which other societies ignore.
