I’ve always liked this Flaubert quote:
Be regular and orderly in your life like a bourgeois, so that you may be violent and original in your work.
I like this Charlie Rose interview with Lou Reed and Laurie Anderson from 2003. Here’s part two.
Among a bunch of other things, they talk about making their art simpler. But I especially love the exchange starting about 4:30 into part two.
“Everybody we know,” says Lou.
“Works,” says Laurie.
