Since this has something to do with two topics of this blog, namely books/reading and translations (or just wrestling with words in general), I'm going to recommend this article from Bookriot, titled "Reading more translated books will make you a better person". It's an interesting text, and I suppose what is said about reading translations also goes for reading books in the language they were originally written when it's not your first language.
It also reminded me of one of my reading quirks, the drive to read outside your favourite genres and/or about times, topics, locations etc. you don't know much about. This not only increases your knowledge and understanding about these topics, but might also make you more tolerant and compassionate. So, clearly, reading is good for you. :)
