The best things in life are free and so can travel the globe. Travelling the world is a great adventure that will stay with you your whole life. Sounds like an expensive adventure you might be thinking. Not necessarily.
There are many ways to travel the world very cheaply and some are even free. Look at the network of friends you have around the world, relatives in other countries, try couch surfing and grabbing every opportunity that comes your way.
You can have an international adventure without needing thousands of dollars to spend. All you need is some original thinking, lots of enthusiasm, the guts to carry on and some ideas to get you started.
