What is the main conflict in Why I Am Not a Painter by Frank O'Hara?

"Why I Am Not a Painter" reflects upon the creative process by comparing the writing of O'Hara's poem "Oranges: 12 Pastorals" with the painting of "SARDINES," a canvas by O'Hara's friend, the painter Mike Goldberg. Told in the first person from O'Hara's point of view, "Why I Am Not a Painter" is a narrative poem in which we see O'Hara dropping in on Goldberg who, at the moment, is starting his painting. After describing the process Goldberg goes through in order to complete "SARDINES," O'Hara reflects upon the process he himself goes through in order to write "ORANGES."
