From The Paris Review interview last year with author Ray Bradbury:

Q: There was a time, though, wasn’t there, when you wanted recognition across the board from critics and intellectuals?

BRADBURY: Of course. But not anymore. If I’d found out that Norman Mailer liked me, I’d have killed myself. I think he was too hung up. I’m glad Kurt Vonnegut didn’t like me either. He had problems, terrible problems. He couldn’t see the world the way I see it. I suppose I’m too much Pollyanna, he was too much Cassandra. Actually I prefer to see myself as the Janus, the two-faced god who is half Pollyanna and half Cassandra, warning of the future and perhaps living too much in the past—a combination of both. But I don’t think I’m too overoptimistic. … It’s the terrible creative negativism, admired by New York critics, that caused [Vonnegut’s] celebrity. New Yorkers love to dupe themselves, as well as doom themselves. I haven’t had to live like that. I’m a California boy. I don’t tell anyone how to write and no one tells me.
