When you are working, everybody is there with you in the studio – the past, the present, your friends, your critics, and above all your own ideas. They are all there. But as you continue your work – digging deeper and deeper – they start leaving. One by one. And you are eventually left all alone. This becomes a crucial point in the life of the work. If you’re lucky even you leave, and the work becomes greater than you could have conceived at the start.
John Cage (composer, philosopher)
