He goes on to make the point that he use procrastination as a filter for his writing - if he feels strong resistance to writing a certain section he leaves it out as a service to his readers - why should they read something that he himself didn't particularly want to write?

"Psychologists and economists who study ‘irrationality’ do not realize that humans may have an instinct to procrastinate only when no life is in danger. I do not procrastinate when I see a lion in my bedroom or fire in my neighbor’s library. I do not procrastinate after a severe injury. I do so with unnatural duties and procedures."
