The author does make a good point about re-evaluating your goals. I can't count the number of years I've wasted chasing after things that, in the end, I didn't really want when I got them.
I hope it's good advice, because it makes sense to me, and I will probably take it to heart.
I see that some people here don't think there's much value in this article. I've grown to believe that different personal/productivity advice like this appeal to and are effective for different people, based on their personalities. For instance I read Getting Things Done, and I just can't keep that up. David Allen must be a machine, I guess. Not me.
