I want to write about failure, but naturally I want to do so successfully--which is to say, not just with aesthetic success, but with commercial success. Of course I run the risk thereby of poisoning the well of my inspiration, but (oddly) this doesn't seem to bother me.
And another oddity. Although D W Winnicott was quite correct to say that 'health is much more difficult to deal with than disease,' it is nevertheless the case that failure is much more difficult to write about than success. It's almost as if 'health' and 'success', and 'disease' and 'failure', do not constitute two pairs of synonyms. Almost as if, indeed, success correlates with disease, failure with health. The very idea!
