Someone's thought of grammar

Many English learners believe that they must memorize all or most of the rules of English grammar in order to be able to speak correctly.
Some students and teachers even think that studying grammar is a "short cut" or faster way to improve their English.
Unfortunately, this is usually not true, epecially for speaking and listening.
When you are speaking or listening , you usually don't have time to stop and think about the specific grammar rules consciously. If you did, you would have to speak ...very slowly.
Most of what we use when we communicate is "unconscious"; that is, we use knowledge that we don't have to think about or even know the rules for.
Here is a very important point to keep in mind:
The best way to be able to use good grammar is to listen and to read English you can understand.
Most native speakers of English can't explain to you the rules of grammar, but they can speak and write English without any problems.
How is this possible?
That is because they have listened and read a lot of English, and they know the rules unconsciously, without having to think of them.
For you to get this same ability, you can only need to listen and read as much as you can in English.
This is what I believe and have been doing.
