“Over the years I've worked out a philosophy of failure which I find extraordinarily liberating. If I'm not free to fail, I'm not free to take risks, and everything in life that's worth doing involves a willingness to risk failure. Although I have had 30 books published, there are at least six unpublished books which have failed, but which have been necessary for the book that then gets published. The same thing is true in all human relationships. Unless I'm willing to open myself up to risk and to being hurt, then I'm closing myself off to love and friendship.”
