This is a very vague question, but I will answer to the best of my abilities. Like any language English is hard to get a hold of, you will make many mistakes, but the best thing I can tell you is to not give up. Make sure to practice English at least once a day, even if it is just playing a english game or watching a movie in English. I also think it is important to learn vocabulary then focus on the structure of the sentence. There is not point in learning the structure if you don't know enough words to make a sentence. Last but not least, have fun! There is no point if you are just learning a language and you hate it, it will take you longer to learn the language.
