When I was younger books had more sway, because well, you are learning the range of human thought. I can recall being impressed for a short time by various books, and maybe they had some kind of influence over my actions. But mostly short range. Eventually, at around age 65 or so, I lost interest in what others were saying in books, and on TV, and in the movies. It all became noise with no pleasure. I far more enjoyed just thinking my own thoughts about what I could observe, or imagining my own fictional stories.
I think one should keep reading, watching, and listening until they have heard all the variations on human endeavors - the mythology of humanity, I suppose. When you've heard the same plot for the thousandth time there's little to gain by 1001. At that point for me, it just became about how I would navigate the final years with the ticking noise growing louder and louder.
