Some metrics you can use to tell quite how busy I am:
-Number of items on my desktop (both laptop and desktop)
-Number of unread emails in my GT inbox
-How many times I've checked my gmail/hotmail/junk accounts
-Size of my physical to-do pile in my room
-Whether I have time to replenish my Krispy Kreme breakfast stash
-Number of items ordered for myself online
All of these numbers are already skewed toward the crazy busy end of the spectrum, and I have at least 3 weeks of business left.
