Learning new words
I have read in one article that it is a good method to set a goal of learning some new words every week, for example 3-5-10 words. It depends on one's abilities, willingness and discipline. I know, when you are a beginner, you can easily learn a lot of words for a short period of time, because most of them have simple meaning, like mother, father, tea, apple, blue, red and so on. But when you are advanced learner, new words need special attention, because you need to understand in what exact situation the word should be used. And bilingual dictionaries sometimes can't help to find the answer, one need to check Collins dictionary, Merriam Webster dictionary and so on.
