Oh, believe me, we appreciate all efforts and I have read on this forum that in Lithuanian there are no articles. I learnt some Finnish when I was 12 and was very confused by the lack of articles in that language too! However, since you already know that this is an issue with your English, it will be very good for you to look closely at every amendment we make to your posts as, eventually, you will spot a few patterns which will help.
My advice is that if you are in doubt as to whether or not to use the article, use it. It will be right more often than it is wrong!
