I read all of these, I swear but I can't answer each one by one I will say yes, I have seen instructors walking around their pupils and correcting their positions like "this arm more to the left and this like that..." So I now understand that obviusly I need an instructor so that I actualy learn something and not just imitate what I see. That is not useful in an actual fight. So well, I will be studying now, and when I have money I will see if I can attend to classes. I see I wasn't thinking right then. If i get an instructor I will ask him everything I need. Thank you for clarifying my ideas!
