I came to Uni in the UK and never went back to my southern European launchpad. (If you're European, open borders make it easy to settle wherever you want.) Regardless of where you end up, I think any multi-cultural experience is incredibly valuable in ways that aren't always immediately recognised or measurable. The advice by others to learn to live with yourself is a good one. Knowing how to cook food that you enjoy is a crucial skill if you don't have a big pocket. If you end up going to a country with a different language resist the temptation to seek and hang around with peers of your own country/language and try to immerse yourself in the local culture as much as you can/like. Contact with other cultures builds character and hopefully opens one's horizons.
