'Learning to let go should be learned before learning to get. Life should be touched, not strangled. You've got to relax, let it happen at times, and at others move forward with it. It's like boats. You keep your motor on so you can steer with the current. And when you hear the sound of the waterfall coming nearer and nearer, tidy up the boat, put on your best tie and hat, and smoke a cigar right up till the moment you go over. That's a triumph. Don't argue with the cataract.'Ray Bradbury, Farewell Summer, p.113.
