"We have a culture that is indirect in the extreme, where by the time you're five years old, you've watched tons of television, and have been subjected to what I call "the age of interruption," where everything is interrupted every minute. We have constant input from TV, computers, fax machines, telephones, etc. It's very hard for a modern American to have two hours of uninterrupted time. I know how it is because I insist on several hours of uninterrupted time each day, and I know how ruthless I have to be to get it."
