My best assistant in learning English is time. No matter how much I learn English, there is need time to complete it in my mind. Even I learn every day, my mind still need free time to regularize thoughts. In Russian language it is sound like "разложить все по полочкам". It sound fantastic, but after break in learning for few days, I feel me more stronger in English :) New vocabulary words easily learned, like as my mind after rest have more free space for new things. Words and grammar rules easily found in my mind. But this case have back side - I can remember new things immediately. It is steel need time and sorting in mind. Maybe it is because I have a lot of trash things in my mind? :)
