Experience, if faced with an open minded attitude, is one of the greatest value we can have. Sometimes maybe we tend to watch things from an economical point of view. If I do this I'll get back that, economically. Of course, deeply we know that it's not the only nor the more important value we can have. I think to handle a different culture, learn a language, being connected with such different mentalities it's a really great value, that may help people economically, but most of it on the human side. It's nice to see you've taken advantage of the possibility you had, even if it may have been hard sometimes!
