If the question is about a productive study abroad, then no, I do not have much to say about that. My study abroad was in the Netherlands where I lived in a castle and traveled around studying art. I did some of the most awful writing of my life and then had that computer stolen once I was back in the States. Essentially, my experience was similar to yours, but with art and the backdrop of the Netherlands and all its wonders (like stroopwaffles, kaassouffle and kroketten!). I also drank most of a small village's supply of whiskey over the course of that semester as I had not yet discovered the joys of genever.
That said, I have had productive times abroad. Each experience has helped me to clarify my understanding of the world and my place in it, as well as my relationships with other people. It's always humbling to walk into a place where one knows nothing of real value in regard to everyday life and try to get by. I am all for people traveling to other places as part of their education.
