Thanks for all the replies and advice.
First of all, as was pointed out, I should have used the word "proficient", not "fluent". Forget I said "fluent". I don't care if I'm never fluent in Japanese. I just want to be comfortable and competent.
Mike Cash, you're right that my life isn't exactly dependent on Japanese proficiency, so naturally, my motivation isn't what it is for you and others. And by the way, I don't tote my dictionary around everywhere. There have been times when I did have it and it was necessary. The point is that, dictionary or not, conversations for me are still usually too slow and awkward.

To the OP: have you ever read a book in Japanese? I'm going to assume that you haven't, or at least haven't read many...You need to put down those textbooks and start observing real Japanese.
Well, if you mean major works like novels, no. I have read short stories, and even some manga, which are supposed to be good examples of colloquial Japanese (and I
have put down the textbooks quite a while back, other than the class once a week.) Actually, my reading and writing skills are quite ahead of my conversational skills. What I guess you're saying though is to not just read, but read enough so it gets in my head and is recognizable when I hear it later. Good point. Thanks for the links, too. Those are great.

In my opinion, the hardest thing to do in Japanese is to explain how to do something. I remember trying to explain how to play a board game called Risk (a fun game, by the way.) Boy, that was tough! Is your Japanese good enough to try to explain how to do something?
It depends. I can give decent street directions, I think. I once taught a girl how to make Mexican quesadillas step by step. I did okay despite my clumsy sentences. Another time I tried to teach someone how to do those number puzzles ("kakuro"?), and couldn't seem to get anywhere.
Anyway, everyone agrees that the main thing is to just get out there and use it, so I guess I'm on the right track. I just need to multiply my efforts by about 10 or 20.
I'd still be interested to hear of any specific learning methods that may have been a big help. For example, someone was telling me recently he'd record a whole TV or radio talk program on a particular subject, and listen to it over and over constantly, looking up every word he didn't know and practically memorizing each sentence. That kind of thing.
Thanks again, everyone. 頑張ります!
