One's belief that one is sincere is not so dangerous as one's conviction that one is right. We all feel we are right; but we felt the same way twenty years ago and today we know we weren't always right.
Igor StravinskyMy 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 one imposes, the more one frees one's self of the chains that shackle the spirit.
Igor Stravinsky
