How to learn a new language

Option 1: Buy a set of books, CDs/tapes and plug in the earphones. Learn at your own pace. Hope the instructors got it right.

Option 2: Move to the country whose language you wish to learn, preferably to an area where no English is spoken. Learn by necessity, with all the local vernacular thrown in. Hope the language is spoken the same way everywhere else.

Option 3: Grab a native hunk from the country, and take private lessons. Learn all the good stuff first. Hope you progress beyond the good stuff without getting side-tracked.

Hmmm.... wonder which one I should choose!? I've got to get Spanish/Portuguese, French and perhaps German into my head asap.... :)
