For me, to be able to speak English, we need to change our environment to be surrounded with everything in English, as much as possible. I believe that input=output. You may need to watch, listen, and read English materials a lot, to get and absorb as much as possible so that when you get familiar with it, you will be able to use it. However, practicing is also the key. You cannot speak by just listening or reading alone. Try finding opportunities to speak and, if possible, finding someone to correct your speaking if needed. If you cant find any, recording yourself speaking and listening to it can help you improve your speaking somehow. Finally, what I want to say is that dont force yourself to study it. Instead, trying to find and do something you love, like watching movies, listening to music, or reading novels of your choice. No need for reciting vocab and such.. you will get it automatically, dont worry. good luck :)
