I've been studying Japanese for a few years. I was recently in Japan for about a month, and while I was able to read and understand a lot of what people were saying, I could barely speak. It was like my brain kept freezing up. It was frustrating, but I'm glad I got the opportunity to know where I'm at.
I'm also starting to learn Spanish because I want to go to some South and Central American countries next year. For now, my goal is just to get the basics down.
