I agree with shaneystar. I never fitted into classroom environments and I stopped going to school completely when I was 14. I do remember those mind-numbing French lessons and I never learned a thing. I'm 48 now and I learned to speak French simply by spending time in France. I wouldn't claim to be fluent, but I can happily chat with French locals and it's been years since someone screwed their face up and said "Uh!".
I remember that I picked up words, phrases and sentences from almost everywhere - posters, menus, hotel literature, brochures, TV, newspapers etc. I took to carrying an English/French dictionary and when I came across a word or phrase I didn't understand I made a point of finding out - even asking hotel or shop staff. I always spoke French whenever I could and I usually found the French to be impressed with my efforts and more than happy to correct me in pronunciation and grammar. That correction became less and less until I can chat in French now and not make too many apparent mistakes.
I've found the same thing travelling in other countries. Before I go I always make a point of learning 'Yes', 'No', 'Please', 'Thank you' and the numbers 1-10 in the local language. Within a week I usually pick up enough of the language to be able to order from menus, order coffee in cafes, ask for basics in shops, ask directions and always being polite to people in their own language.
I don't think anyone ever learned much in a classroom (what percentage of British 16 year olds are fluent in a foreign language?) You've got to get out in the world to learn.
