Actually I have an experience working in 10 countries because I was an International Sales (ha-ha)
However there is a big difference of having 1 year trip to FEEL the world ( and then go back home) and Go to conquer the world ( usually for money or to grow your business there)
That's why I am asking ...
The UK is nice for new experience however I know many many people from the group #2 who have tried but failed to make a good business or even finish the university there .
So the answer could be - have clear goals ( business or pleasure) , get more information, be strong but have a nice plan B in your pocket
