I think it depends on your level and discipline to learn English. It would be shame for someone to study in boring, rote ways for the sake of short term goals (i.e. TOEIC Exam). Too many English learners do this, and what happens eventually is they lose interest, or worst, associate a strong disliking towards English. I would begin with watching movies, TV shows, youtube videos, or listening to songs, podcasts, etc.; anything that would interest you spoken in the English language, and to follow this habit gradually. Perhaps, 1-3 times a week to begin. This way you will learn to actually like the language and learn for the long run. Learning English, and any language, is marathon, not a race.
