Zbigniew Herbert said this quote

Very early on, near the beginning of my writing life, I came to believe that I had to seize on some object outside of literature. Writing as a sylistic exercise seemed barren to me. Poetry as the art of the word made me yawn. I also understood that I couldn't sustain myself very long on the poems of others. I had to go out from myself and literature, look around in the world and lay hold of other spheres of reality.
