Once you have started to learn a foreign language you want to use it, speak it, write it and above all communicate with others. But as we say, you have to learn to walk before you can run. You have to learn something about the way words work together, the way you can express different times or tenses, the way you use adjectives, adverbs, prepositions and so on. But if you are determined to get control of the language, understand it and use it properly, you must not let the things I have listed stop you. One thing at a time. Gradually bit by bit if you work hard, you will find success. The one word that sometimes makes people frightened when they start to learn a new language is "grammar". But don't worry about that word because it's only a very general title used to cover the workings of the language. The danger comes when you let grammar get in the way while you are learning. Remember that it was people who created the language in the first place. The "grammar people" or the grammarians came later.
