Stravinsky

"My freedom thus consists in my moving about within the narrow frame that I have assigned myself for each one of my undertakings. I shall even go further: my freedom will be so much the greater and more meaningful, the more narrowly I limit my field of action and the more I surround myself with obstacles. Whatever diminishes constraint diminishes strength.The more constraints on imposes, the more one frees one's self of the chains that shackle the spirit"

Igor Stravinsky
