How to learn der, die and das properly

I am learning German for couple of month and already grasp sufficient knowledge on German grammar upto a1 level but I think I have to stop know. I can't remember the articles of nouns. I try to memorize the vocabulary with articles but after some time I forget the article while the vocab stays on my mind for long time. Tried learning with flashcard also but here the same problem occurs (I always forget the article). Should I stop now? I think this language is not for me
