Hi, I believe the quickest way to learn a language is to have a tutor or a teacher by your side, especially if you are at the beginning levels because a teacher knows students' weaknesses and strengths, and based on those, he/she will choose the material to be taught. outside the classroom, it's the students' job to get as much exposure to the language as possible(meaning that you must try to read and listen to different things in that language as much as possible.)

I find friends, language partners, and learn about things I enjoy. When I'm teaching them English during our language exchange, and they make a mistake, I ask them how to say that in their language (which I'm learning). This helps me prevent from making the same mistake when I speak their language. These tricks are interesting to me, so I learn quickly.

Toy with the idea for a while. Go do something else. Do it better than I do. :) . Let us know your way to learn a new language. - Ok. as In tell everyone here. :)
