Halfway to healthy?

It was a sobering reminder that our little group initiative is reaching its halfway point.  I'm challenge-oriented and sense a bit of unease when considering leaving this haven, this community of accountability and starting out alone.  I'm unsure of myself.  I have not created this obese beast by abiding by the laws of healthy living. Luckily we have a few more weeks to develop more will-power, more self-discipline, more long-term awareness.
