Speak English fluently is the most important

Most English students start to learn English with only one goal which is "to speak English fluently", then they follow some boring methods (grammar, memorizing word lists) then they end with a different goal from the goal they started with.

Always put in your mind that speaking English fluently is the most important thing in your English learning career, English grammar and all other methods are just useful things and ways which can lead you to the goal.

Studying English grammar makes English students think only about grammar and the structure of the language.

Please tell me: which one is the best: to speak English fluently with correct grammar without knowing grammar Or to know everything about English grammar but don't speak English fluently?

let's talk about memorizing word lists: Which one is the best: to have a limited vocabulary you can use easily OR to have a huge vocabulary you can't use?
(But I want you to have a huge vocabulary you can use)

Always put it in your mind: English grammar and memorizing word lists are not goals, your most important goal is to "speak English fluently".

I think everything is clear now, but I want to ask you a question just to read your comments:
Do you have a:

1-Huge vocabulary you can use.
2-Huge vocabulary you can't use.
3-Few vocabulary you can use.
4-Few vocabulary you can't use.

I'm waiting for your answers in the comments, hope to see you for the next tip.
