Ok, I'm going to start this off with a question : Is it better to travel while you are young?
No matter how I try to spin this, as with most decisions in life, there are positives and negatives. But, due to personal preference, I am firmly in favour of making that easy decision to take the leap, getting out of your comfort zone and explore the world and all its cultures, places and people.
There are so many different ways to go about it, too much for me to explain in this post (watch this space) but if you are granted the opportunity to live overseas, do it.
Rather regret the things you've done than the things you didn't because you were scared of what MIGHT happen.
