in my opinion...just listen more and and practise more ....but these things just based on the basic rules....

hi!=) in my view u should learn the crucial sentences as well as basic rules of the language. your question is something like "what's better: to breathe or to eat?"=)))

It depends on the person, but generally speaking I think you can learn a lot by narrow listening. Narrow listening means take a topic you already know and hear similar podcasts of this topic. Sure you need some basics to get get there. And I think you really learn a lot when you already understand about 90 % of it. Therefore take simple things first. And never overburden yourself and have fun while learning. Djuha
