Which is more valuable for personal development, reading a novel or reading one of those reasoned books, and is reading a novel worthless? And reading books is recommended to be read one after the other. You can read into whatever genre is right for you, but pick something worth reading based on your own preferences. Some people can learn to be a man even from martial arts novels, some people read thousands of books without knowing the reason, it is better not to read. It is better not to read two or three books together, I usually read one book after a few days and then read the next one, sometimes reflecting on it, and will find the unanswered questions again and again. The same goes for novels.
