That choice to be ready to reject all other purposes, in favor of the possibilities of language freed from utility, is when the writer becomes a poet.
I had this idea for a long time to make a film about a poet in Paterson named Patterson. I wanted him to be working class. Eventually I thought a bus was a perfect visual way to move him, to drift him through the city, to have a measured kind of routine lifestyle. And all these things kind of congealed into the film "Paterson" eventually.
