There's so much to see in the world, and you are so excited that you're going to go out and experience it. Even for a mature traveler, overseas travel can be stressful. However, for a first-time traveler, it might be completely overwhelming.
First, there's the pre-trip planning, such as getting a passport if you don't already have one, applying for visas, deciding where you'll stay and how you'll get from point A to point B. But the beauty of travel is that you don't have to know everything; it's a learning experience. As long as you have some basic information to cover the most critical components of your first international trip, you'll have plenty of room to develop and learn, as well as gain some confidence for your future journey overseas.
