I believe that the most dangerous state in learning is when you already know the minimum of information and you are able to use it. Ususally after this you loose any interest in learning and you feel like you know much enough to survive.
This is what I am trying to overcome. I’ve been learning English for the past few years and now that I can speak it, it is really difficult for me to learn something new. But I also understood that when you you know something, learning gets more interesting.
