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.
When you are working on external projects (however not only) you put more time to schedule, because you are afraid about the unpredictable things. All of that is because all delays cost you lots of money. However in many cases you don't need to do it. In many cases finishing tasks as soon, as it possible is much more important than having some time, which was scheduled for something unpredictable. Especially when you are working on your own projects.
That's the point of Parkinson's Law.
