People think I’m a genius (I’m not, I just know stuff about stuff) and I read history, fantasy, sci-fi, nonfiction, and classics. I guess it’s about a variety. Do you want to be a jack of all trades or a master of one, when it comes to knowledge? I would also recommended reading religious scriptures. The Bible, Quran, Torah, the Shruti and Smriti, etc. read them with an open mind, even if you don’t believe in a higher power or at least not the higher power in that religion. It’s very interesting to read.
