Here is a charming little paragraph from Paul Muldoon - his 'Author's Statement':
'I'm afraid I can't come up with anything wonderfully witty and wise to say about my work, except to wish that it displayed a shade more wit or wisdom.
The truth is that I hardly ever read it, let alone theorise on it. I'm much less interested in what I've done, which almost certainly amounts to very little, than with what I might do which will almost certainly not amount to much more.
I'll keep trying, nonetheless.'
