“For now, what is important is not finding the answer, but looking for it.”
― Douglas R. Hofstadter, Gödel, Escher, Bach: An Eternal Golden Braid.
If you get stuck, get away from your desk. Take a walk, take a bath, go to sleep, make a pie, draw, listen to music, meditate, exercise; whatever you do, don't just stick there scowling at the problem. But don't make telephone calls or go to a party; if you do, other people's words will pour in where your lost words should be. Open a gap for them, create a space. Be patient.
― Hilary Mantel, The Guardian, 25 February 2010.
