There are some articles that I found hard to understand for me. I do not know if texts can really be rated as hard, medium, or easy to be read or understood. But if they're really are, I would like to know how to comprehend those which are hard or medium. I can hardly understand a phrase like,"The end does not justify the mean." This is a famous phrase, but I don't know exactly what does this mean. I'm not an American or British that has a, if not great, good command or knowledge of English. But I would like to understand phrases like this.
