Jeanette Winterson said this quote

Wide reading is important. You don’t have to like it, but it’s important to grapple with things you don’t understand. I’ve been spending the last six months getting up an hour early to try to understand economics because I need to. I don’t want to be one of these bewildered schmucks. The things that you understand will inform your writing. The bigger your mind, the better your work is going to be. You’re not born with a big mind; you have to build it. If I don’t read for an hour a day, I get ill.
