There are many approaches to learning a foreign language — the Army Method (stress on learning through memorization), the Grammar Translation Method (learning a language by parsing its grammar), the Communicative Method (leaning by speaking and listening in the target language), and the Natural Approach (trying to replicate the steps that children go through when they learn a language). Then there’s the “get attention” method, which I’ll label the Social Feedback Method to give it a proper name. Basically, you learn whatever vocabulary and phrases that will make you the life of the party among your target linguistic group, be it fun ways to begin conversations with attractive Japanese girls or memorizing interesting phrases that will amuse people around you, like esoteric proverbs they don’t expect foreigners to know. I have a friend who worked his way across Asia using this method, learning just enough of the local languages to be social and have fun with his hosts, and it seems to have worked very well for him. Bottom line, when you study a foreign language, make sure to keep your eye on the “fun” aspects of that language.
