I am Chinese and am crazy about learning languages. I think they are fascinating. Besides,I have tried picking up various/multiple languages simultaneously such as English, Japanese and Spanish, but, it works inefficiently.In my opinion, if you are an absolute beginner, the most efficient way to master/ace the language, is to choose only one language and stick to it. After attaining a conversational level in the language wherein, you are able to use the language on a daily basis, without commiting numerous mistakes, you are ready to start with another language. Remember the fact that there is one heart for one thing.Following the procedure, step by step,you can be ace all the languages you wish to learn. Thank You for reading.
