The thing is I was really good in school because I didn't really know what I wanted to do later on, so I learned pretty much everything I was given. I mean, I guess I always knew it was going to be computers but it's not like I was a really young programmer or anything like that.
Regarding freelancing, I have learned a lot even from client work but I can see your point; lately I've been doing the same repetitive Wordpress coding gigs even though I would really fancy learning Rails.
I can't really say I'm interested in any other domains since I hate math, physics, etc. I do love design though, but I'm not sure how art fits in with what you were thinking.
Regarding college, moving abroad is exactly what I plan to do, but I can't say I have everything planned out yet, but I'm not sure how helpful a CS degree would be in my case.
