Hard but not impossible
Learning a new language is not easy. It is hard for adults and busy people to learn a new language that sounds differently from their mother tongue and that they don’t use outside the classroom.
It is really hard, but not impossible. Recent studies suggest that you can get better at a foreign language simply by listening to it, without speaking it yourself.
In other words, if you listen regularly to podcasts in the language you’re trying to learn, you will learn it at the end.
One hour listening practice a day following with some simple tasks is a good start to improve your listening comprehension and increase your ability to distinguish sounds.
Also, it is recommended to watch TV shows or short video clips and read material written in the language you are learning.
The goal is to be surrounded by the target language at all times and immerse yourself in it. Still, you should be both passive and active when you learn a foreign language, that is to listen and speak, read and write. In other words you should receive and produce something in the language you are learning EVERY DAY.
