If you think of movie studio executives, say, as society, then I root for the independent producers.

If it weren't for received ideas, the publishing industry wouldn't have any ideas at all.

There are a couple of writers I admired who were very good at giving the character's emotion without stating what that emotion was. Not saying "He was feeling tense," instead saying, "His hand squeezed harder on the chair arm," as if staying outside the guy. I wanted to try doing that. I wanted to have a really emotional story in which the characters' emotions are never straight - out told to you, but you get it.

Science fiction is a weird category, because it's the only area of fiction I can think of where the story is not of primary importance. Science fiction tends to be more about the science, or the invention of the fantasy world, or the political allegory. When I left science fiction, I said "They're more interested in planets, and I'm interested in people."

I don't think I ever have trouble with writer's block. It's different when you make it up as you go - that means you're going to get stuck. I wouldn't call it writer's block, I'd say, "I don't know where the hell this story is going."

All of the changes in publishing since 1960 are significant. There are far fewer publishers.

Years ago, I heard an interview with violinist Yehudi Menuhin. The interviewer said, "Do you still practice?" And he said, "I practice every day." He said, "If I skip a day, I can hear it. If I skip two days, the conductor can hear it. And if I skip three days, the audience can hear it." Oh, yes, you have to keep that muscle firm.
