In case anyone's interested - today's magic number was 30, and I just completed the exercise set. Which means that I've accomplished my first self-improvement goal in, well, essentially ever.

Sure, 30 toe-touches/sit-ups/etc a day isn't all that impressive compared to what a lot of people are capable of - but it's 30 a day more than I was doing a month ago. And starting tomorrow, I have a new plan: burpees. Again, few to start off with, but more every day, until either something breaks, or I decide to do something more interesting.
