I couldn't quite understand the message due to all the extraneous commas, but it seems to be the same one Ferris talks about in 4 Hour Work Week.

Also, it mentions unexpected crap popping up but not how to deal with that. It's like, OK, let's add some more time to our project schedule. But wait! We gotta take some off due to Parkinson's! You end up with the same damn schedule.

I really think this piece would be a lot better if it had been thought about/revised more, 'cause as it stands it can only serve to reinforce whatever point the reader -thinks- it's about.
