Does quality matter more than quantity when you want to learn a foreign language?
Not true: Too often do language learners (and teachers) forget about the importance of quantity in the language learning process, in terms of input as well as output. Being the perfect student during your lessons at school or in any other formal classroom environment is not enough to become proficient in the foreign language.
So many students are left behind in school settings because they are not engaging with the content presented to them by a teacher or the course book. Too much time is spend on explicitly teaching the learners about various aspects of the foreign language and too little time is spend on letting the learners become creative and make the language their own. If students would receive more input and be asked to produce more output without a focus on perfection, they would be much quicker in learning the language, especially in the beginning, and enjoy the process much more without sacrificing accuracy in the long run.
If you want to become proficient in the foreign language, try to expose yourself to as much input as necessary. Read and listen to a variety of sources without being too worried that they are not sophisticated enough. If you want to read tabloids, then do it. If you like watching films, watch films that are available in the foreign language. If you want to get better at writing, start writing. You don't need a teacher to constantly tell you what you could do better. Start writing as much as you can and about anything you want to. Have fun, enjoy it. Speak as much as you can without overthinking every sentence. It does not matter if it the outcome of your efforts is not perfect, in the long run you will get much better.
If you want to become proficient in a foreign language, you will need to focus as much on quantity as you do on quality.
