Learning languages efficiently.

I’m not at all sure how this site works yet (I’ve gone only on traditional forums), so bear with me please if I do something foolish. I’m being drafted to the IDF in a few months and I need to learn Hebrew very quickly if I want to avoid being put into a program for foreign speakers. I currently reside in the US, but I’ve previously lived in (and have citizenship of) both countries.

After experiencing the government-sponsored Hebrew programs, I totally refuse to accept such a ridiculously inefficient and traumatic method of teaching a language. When I get enlisted, I’ll want to focus whatever little time I have left on studying more important things. Something that will damage me psychologically, not to mention take up huge amounts of time and effort, will take away any opportunity I might get.

I can speak a few basic phrases in Hebrew and and can understand a bit more. Immersion is not an option for me currently. My attempts at teaching myself the language have been stunningly misguided (which is to say, like reading Atlas Shrugged to get a proper understanding of Objectivism) and I’m not interested in a lengthy trial and error process. Obviously getting literature on language acquisition is out of the question. I wouldn’t even know where to start.

So, I’d just like some methods or heuristics for picking up languages as fast as possible. (I am extremely literate, so there’s that.)
