Interestingly enough, this goes somewhat against the PG essays "How to do what you love" and "Good and Bad Procrastination" which I just recently read.
I guess he has a point in that there are problems that have to be dealt with and you should go peak into unknown areas from time to time, but generally, I think I have to disagree based on the stuff I learned from PG. Finding someone that loves doing what oneself is avoiding (procrastinating) should be a better solution than self-punishment (I second virtualmice's comment.)
Also, I don't like his tone. It's not quite written as a rant but sure sounds like one.
