studing hard, taking with natives speakers, keeping practise estudiando duro, hablando con nativos hablantes, no dejar de practicarlo

I answer about French. Such questions are too relative! Because, it depends on many factors like: your level, if you’re studying it as a major, are you in French speaking surrounding ....etc. The most classic answer is: practice, listen and speak! These things are tools more than methods. That’s why you should find your own way to do it, because what could be adequate for someone wouldn’t be for another. So, if you started to learn recently I advise you to begin with easy texts and audio-books. Like children tales or songs with lyrics, they are efficient for the beginning. Then you can pass to other audio-visual learning material. I didn’t use French learning material except what we used in school, but I heard of a method called “Reflet” that private schools use. So if you can buy it or rent it, it would be very helpful. Good luck,
