By the way, just to elaborate on what I meant about doing your own experiments to convince yourself either way, here's an excerpt from my own blog:
2007 shall be the year of my Great Experiment. I shall set huge goals for myself. They should be so huge that it would appear impossible for me to attain them through normal means.
Except that I do not intend to employ normal means. That's where the experiment begins.
So you see, dear Markus, I'm doing an experiment too. As I see it - what is the
worst that could happen? At the end of 2007, I would feel rather foolish about myself. Ok, I could live with that.
What is the
best that could happen? Ahhhhhh.

It will be ....
ABSOLUTELY AWESOME.
