Science fiction is not predictive; it is descriptive.... Prediction is the business of prophets, clairvoyants, and futurologists. It is not the business of novelists. A novelist's business is lying.... Open your eyes; listen, listen. That is what the novelists say. But they don't tell you what you will see and hear. All they can tell you is what they have seen and heard, in their time in this world, a third of it spent in sleep and dreaming, another third of it spent in telling lies.
Ursula K. Le GuinI have never heard a dancer asking for advice about how to stay focused on her footwork, or a painter complaining about the dull day-to-day task of painting. What task worth doing isn't worth daily effort? Do you think Michelangelo was having fun the whole time he was on his back painting the Sistine Chapel's ceiling?
