Learning more than one language, it's excited for language lovers or polyglots. Many people tries hard to learn multiples foreign languages. They learn multiple foreign languages because they want to explore this world but it would be terribly difficult. Imagine! how long can you maintain your foreign language skill and remember many different words on your mind? The best solution is living in a foreign country where your target languages are spoken and have many foreign friends there. But it's very expensive, living aboard is not easy because we will leave our homeland, families, friends or environment temporarily but it's fun because we will get memorable experience but we will also feel homesick and suffer from culture shock. And if you feel comfortable with new environment (in a foreign country where you want to live), you probably won't come back your own country.
