They say travelling is the only thing that you buy that makes you richer. But there’s a huge difference between travelling alone and with friends.
Travelling alone gives you the freedom to do as you will. No one to explain stuff to, nobody to report to. But travelling with friends is a whole new experience. The fun you have, the memories you share, those will last forever.
So, if you want my advice, do both. Go abroad with your friends. But make sure you speak the language, or you’ll never hear the end of it.
