i think that you should start with yourself. the only thing that i can say is just read and listen. read graded book in you level. check every words in the dictionary at the first. you whould find it hard but you should do for start.
watch you favorite films in English and try to find it out what it says. see the film several times and use the dictionary less that when ever, because the film is something else. it's like that you are with people and you can't stop every time to check the new words in the dictionary.
