"The parts I like, well..." He shook his head, with pursed lips. "They just don't have anything to do with me: somebody else wrote them, it seems, about things I may have thought about once. The parts I don't like--well, I can remember writing those, oh yeah, word by word by word."

Perhaps it's good you're not going to write anymore: you'd have to start considering all those dull things like your relation to your audience, the relation between your personality and your poetry, the relation between your poetry and all the poetry before it.
