Interestingly Enough...
I've cleared a small plot to begin growing veggies for (at least some small) profit this year.
I can't see myself getting completely out of IT - the constantly changing landscape sooths my ADD. And, as Three Dead Trolls says "nothing beats the adrenaline buzz of getting a guy's DSL modem working, even though he's on a 386 with 2MB of RAM" ... or whatever problem I can solve that at first seems unsolvable.
However, there is a certain attraction to being able to point to an actual product and realizing that your work resulted in something besides a paycheck.
