"What are the three items that are dearest to you in the world? Who are the three people that mean the most to you? What are three things that you would most like to try? Write your answers to these questions on nine separate strips of paper. Then choose the three that you’d be most willing to live without. Crumple them up and throw them away. Now choose three more to discard. Now two more. Finally, throw away the only one that you have left."
