Trying to become smarter

I love knowledge. Ive always wanted to be full of it and be the best I can be. Literally, my hobbies consist of studying, documentaries, podcasts, and TV on things im interested in. But I want to get back into reading. I was reading the cherry ames books by Helen wells, now im reading "Sourrounded by idiots" by Thomas Erikson.

After, im gonna read "To Kill a Mocking bird"

So ive read books on my interests, psychology, and im gonna read a classic. What other genres should I read to become smarter and more knowledgeable?
