Learning a language is an authentic WORK. You need to practice every day in every single area.. from listening to speaking, writing .. futhermore the grammar, reading.. uff! When you achieve an intermediate level, sometimes you could slow down with the practice. .. but this is dangerous because you could use every time the same words or structures.. It's a pity! I'm aware that I need to read more, for example, or maybe I could need to watch a movie in English.. but sometimes I'm so tired!
