Hey man, before speaking I recommend you consume as much of the language as possible. That would REALLY help you get the hang of it. Meaning consume a lot of content in english but also be focused when you do. Music, movies, youtube videos etc. And while you listen, if some word stands out, look it up. Then I also recommend you read a lot of english books but read them out loud so your fluency improves aswell. If you dont know how to pronounce a word, check it out on google. Dont be shy to use the right pronunciation too. We tend to think we're being too much when we speak the right english in this country but you shouldnt care. And some books are more difficult than others so pick a topic youre interesred in but something not too complicated to start with. Another thing you could do is write english. Journal everyday. That will REALLY boost your english mastery. Since going out to find people in real life might be too much effort, use discord. Its like a social media app(kinda) but you can find servers there that are fully focused on improving language. Look for english improvement servers and you can talk to people thered every day on calls. And since everyone there is either there to improve or to help others improve, you can feel free to make as many mistakes as you want. Good luck👍
