Do you think It is possible to learn a language by your own?

The portions of your paragraph that I've highlighted are incorrect. The first problem is with the wording that you chose. It should should be, "yourself and achieve proficiency." Or, "yourself and get to a good level," if you wanted to be less formal. There are different ways to format the phrase that you're trying to express, but the way you chose to express it is grammatically incorrect. The second problem is that you would be in your own country, not on your own country. Hopefully, I helped you a bit in your journey to become an English speaker. Unfortunately, I'm not an English teacher, and I don't know the intricacies of English grammar, but I am a native English speaker and a college student, so I think I know enough to correct the portions that were clearly incorrect. And as for your question, yes, I do believe that one can become a proficient English speaker while living in a foreign country, however, it's important to remember that learning a language is a process that will take your entire life. I have lived in America for all of my life, and I am still learning new things about my language. Unfortunately, many people become obsessed with the idea of fluency, and they get dissapointed early in their language learning journey when they haven't achieved the goal that they were aiming for. If you can come to terms with the reality that learning a language will be a life long process, then I would say you're setting yourself up for success. Oh, and your paragraph, other than the problems I highlighted, was good, so that's something to be proud of. [emoji]
