I want to be a globetrotter

There is nothing wrong in dreaming big. You could always travel all over the world, provided you have arrangement for financing your trip, you have sufficient time at your disposal. You could start step by step, if it is not possible to visit all the major countries at one go. You could go continent wise. All the best.

first thing you can do is save money. that is how I managed to have a vacation in Sweden. you should also try learning other languages. its easier to get visa if you speak their language.
