All poetry comes from repetition.
Picasso said once when being interviewed that one should not be one's own connoisseur.
Poetry, which is written while no one is looking, is meant to be looked at for all time.
I love painting and music, of course. I don't know nearly as much about them as I know about poetry. I've certainly been influenced by fiction. I was overwhelmed by War and Peace when I read it, and I didn't read it until I was in my late 20s.
You can't be too influenced by a great poet. You simply have to live through it.
When you finish a poem, it clicks shut like the top of a jewel box, but prose is endless. I haven't experienced an awful lot of clicking shut!
