my name is Moises I am from Mexico and I have a lot of time trying to learn English,I have bought a lot of courses but I can't learn completly, I have studied too much grammar though I can speak and write very well, when a native speaker say to me something I can't understand him and I get nervous and my brain turns off.

I listen various podcast and I think my ear is being able to recognize some sounds, some peoples say me that  I have to watching movies and songs and to try to repeat all they are saying something like "mirror" I hope you can help me and finished this that I have studied all my live, well, I big part of my life
