As a language learner you don't have to force yourself to memorize new vocabulary by heart using long list of words, and this is the reason why I think it's the case: Firstly, if you read a lot; You don't have to memorize words at all, let me explain to you what I mean by that. With a lot of reading, you encounter new words for the first time, so what do you do then? Yes, you explain their meaning and understand the context in which you encountered them in. Based on that, what I suggest to you through the experience I went through is to not try to memorize these new words by heart, but rather to just understand the meaning of the context they came in when you encountered them. Here I suppose that you read what you are interested in abundantly, if that is true then be sure that many words will frequent you more often than others (I am not talking here about conjunction words or common verbs...etc) but I mean words that have a direct relationship with the field in which you read about and you are interested in. In most cases, our interests affect our vocabulary - of course not completely - for example, if you are interested in psychology and read a lot about it; I think that your vocabulary will be richer with psychology terms more than someone interested in programming, for example, but not limited to; Thus, you will encounter more words directly related to psychology more than other words, without forgetting the basic condition that lies in the abundant and continuous reading; Because if you read poorly; It won't work for you, or at least won't be as effective as it should be.
