How should we learn grammar? - Some useful tips

Script:

Hello! Today I wonna touch on a very thorny subject as far as language learning it's concerned and that is grammar, some people believe that grammar based approach is key to efficiently learn a language xxxx I think that xxxxxxxx                     study is necessary  for understanding the structure of the language They insist that without grammar, without grammar books, It will be impposible to dicipher the language itself ,and the language will just be a jummble of words, an uncomprenhensible jummble of words, so.. some goes as far as to say that you need to learn grammar even before tackling the language itself , I call this approach a purely analytical approach, On the other hand, there exists another school which I call a purely deductive approach...according to which.grammar books especially at the beginning xxx is just no necessary obstacle to language learning , It just slows down language learning, letteraly slows down language learning xxxx...just we have to do (sparse) as far language learning is concerned..is just attack the language directly ..so..here.. the key words are massive exposure, and deduction. the art of deduction....now..I wonna to share with you my personal vision on this topic and just want to start by quoting a phrase here that I found on the internet ..and I'm going to read..and here It says...;"Grammar is the structural foundation of our ability to express ourselfs.The more we are aware of how it works The more we can monitor the meaning and effectiveness of the way we and others use the language. It can foster precision, detect ambiguity, and exploit the richness of expression. This can help anyone xxxx   English teachers but all teachers of everything xxxxxwas the phrase "the more we are aware of how it works ...well...You know..   Idon't think we need to be aware of how it works that's a problem we just have to make it work ...I thimk ...once one is able to speak a language to make it flow ..and ..once a language is accurateli expressed ..you have internalized grammar...unconsciously. Now....five years old kids, for example xxxxxxx unconsciouss of the concept of grammar , but they do speak a language xxxxx . I think that as far as the school system is concedrned  They propose a very inefficient approach ..the problem in general with adults but this is humanity    I think in some issues ther4e is a tendency to catgorize the world. Now for example...as far as purely scholastic subjects if we consider purely scholastic subjects like geography, like history for example, Or...i don't know Biology, Pilosophy, etc. Dividing material into smaller categories can actually help you understanding better caus you divide in
