Although I've already studied 3 languages (English, Persian and Russian), I never tried to learn any of these languages in a short time. Now, I want to learn German, and I want to learn it as soon as possible :)
I'm trying to learn German everyday for several hours, but after certain amount of time studying, I'm starting to notice that everything I learn will be stuck in my short-term memory and I'd forget it all the next day.
So i wast to know whether you face such problem while learning foreign languages? How many hours a day is considered OK so that you'll actually learn new things and not just memorize for a couple of hours?
