Personally, I don't think this task is really all that out of reach. The items so far on the list are, for the most part, rather easy. So I was surprised when I mentioned it to a few people the responses I got went something like "You're never going to be able to do that in 30 days", "You're nuts", or "You will never finish because you couldn't not be negative for more than 5 minutes" - followed by laughter.
So here's to the Naysayers! And here's to finishing what I started!
