The method that works best for me when learning a new language is reading in that language. Read, read, read as many books in English as you can. Of course, an online tutor should help quite a bit as well.
And concerning the grammar in your message; it isn't that bad. The two main things I would change are: When the letter "I" is referring to one's self, it should be capitalized. You should also leave a space after you put a period.
-[this is wrong] Here is a sentence.Here is another sentence.
-[this is correct] Here is a sentence. Here is another sentence.
I hope that helped. If not, let me know.
