I realized that I agree with the messages in the medium of the book. I think they are true. I think they encourage the best parts of human nature- that a life with lots of episodes of deep focus is a good life. It is why reading books nourishes me. And I don't agree with the messages in the medium of social media. I think they primarily feed the uglier and shallower parts of my nature. It is why spending time on these sites even when, by the rules of the game, I am doing well, gaining likes and followers leaves me feeling drained and unhappy. I like the person I become when I read a lot of books. I dislike the person I become when I spend a lot of time on social media.
