In my opinion,The most difficult part of learning English is that one couldn't develop the interest of English, you'll find it's boring if you couldn't enjoy the fun of learning it,and will waste a great many effort without any progress,The methods of learning english varies from one to another,and i think some so-called better way are not necessarily suitable for you,you may as well find a way of your own,and most importantly,enloy the fun of english!
wish you succeed!
