We fought during 'The Wall,' which was an album Waters wrote, based on his family story, we clashed long before that, during the period of the Dark Side and 'Wish You Were Here.' Actually, we never got along.

We worked very hard to make the lyrics suit the music. I can't, like Elton John, for example, compose by lyrics. Elton has a great talent for that. Whatever you give him, including your questions, he composes in half an hour and makes a great song out of it.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.

To ask questions can become the laziest and wobbliest occupation of a mind, but when you must yourself answer the problem that you have posed, you will meditate your question with care and frame it with precision.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
