@albertbrine,
I am sure that in your country there are books how to teach yourself English.
There are a book and almost always a work book - often with the correct results at the end.
You should be able to control your mistakes.
Maybe there are evening classes where you live. It is a good idea to take part in that as again you will not only improve your vocabulary, but also your pronaunceation and your ability to speak.
Always look up words you do not know and write them down.
Have them on a loose, small paper, which you can flip over.Write in English on one page and your language on the other page. Put them in a box and every day see if you know the words. Not all of them at the same time.
That way you can control how you improve your knowledge.
