What do Challenges mean to me

Now this is a tough one. While I'm a competitive person, I also am not. The challenges we have been having have been very good for me even though I've not done well on them. They are making me take a good hard look at myself and my lifestyle. I see the things I need to change and don't think I'd have looked hard enough to find them with out the challenges.
The last couple of challenges have given me new motivation to do something productive about my weight and health.
I hope each and everyone on the challenges are making positive progress, even if it isn't on the scale.
