major obstacles and expectations

Major Obstacles : 
learn english in my experience many difficulties as in pronunciation, often I am wrong in pronouncing words. difficulties in conversations with others, because only other than that I find it difficult to understand grammar because it is too much to comprehend.I have trouble to understand the divers between noun,  verb, and adjective and ofcourse the usings of tenses.

expectations :
I wish that I could be better in pronunciation of words, to improve the conversation. I also wish that I could understand that there are more grammar, so if I write a sentence no one put it. and a good sentence.
