I really liked his book "The Art of Procrastination: A Guide to Effective Dawdling, Lollygagging and Postponing". I read a lot about procrastination, as a form of procrastination.
It's not all bad, of course. But it can be a problem. These professors writing about it clearly has managed to make it work for them somehow. I guess the grass seems greener on the other side of the procrastination spectrum.
