Just take a train to the country next door and stay in a youth hostel. You don't need a car or lots of money, but you do need a budget and sense of adventure. Meet interesting people. Students who study abroad make contacts all over the world. Whether you want to practice a language, learn about a culture, or network for job prospects, people are your greatest resource.
Many students return from studying abroad with friendships that cross cultures and last a lifetime.
At the very least, you are guaranteed to meet people with a different slant on the world. Others in government from William J. Fulbright to George Bush have echoed similar sentiments. Study abroad might not just change your life, but the world. Find your calling. For those unsure of what to do with their lives, study abroad can be an inspiration.
