It seems to me that people attach great importance to grammar when learning a new language. This slows their progress. And it makes it difficult to speak. And in my opinion this is a big mistake. Because communication continues as long as a tourist understands even a wrong sentence. That's why I think more words should be learned without focusing on grammar in the first stage.

The biggest mistake I have seen people make while learning a new language is that they focus too much on vocabularies. They spend a lot of time learning new words, but they do not know how to properly use them in a sentence.
