The most effective way to learn English is to let your subconscious do the work for you. You'll need as much speaking experience as possible to do so, which I can help you with! If someone enjoys what they are learning, it will come to them more easily. If all you do is study in a classroom or watch English content online, when you find yourself needing to speak or write in English, you may struggle. You cannot just memorize the sentence structure for every sentence you will ever make. You need to learn to think in English on the spot, and develop your own go-to phrases. The best way to do this is to immerse yourself by speaking with English natives.
