Just as the saying goes:practice makes perfect,so practice is very important first.
Secondly,where there is a will,there is a way,so persistence is what you need exactly especially when what you are doing is very difficult.
Thirdly,if you have an interpretation book to guide you and learn interpretation step by step,this will be a very good shortcut fou you to be on a right way.
Anyway,to be said is easier than to be done,so have a start immediately and never give up,and you will be on the way to success soon.
