I use to read a lot. When I was a child, I read books like there was no tomorrow. Of course, I did not understand everything, but I kept reading and looking things up in the encyclopedia set my parents had gotten for me as a child. My main genres were science fiction and memoirs. Books are great because they tested your imagination and would provide fodder for you to create a world in your mind. Pictures work in a similar matter as books, but without the text, you have basically just an image or several images telling a story.
