Yes, on German so many times. Most of the times it was because of the teachers that just sucked all the fun out of learning the language. It's hard to stay motivated when the teacher doesn't do much in class at all. So when I saw that this was leading nowhere, I just decided that I would start learning on my own. And it worked out for me, because I got the grip for the basics of the language much better and faster than I could ever before. Now I'm pretty confident in my speaking ability, though my writing does need some improvement.
