Awesome post! You can do it! Sounds like some good goals and good plans. I feel that same way as you. I definitely have a few pairs of pants that don't fit anymore. The worst thing I noticed was the getting winded like you mentioned. I'm finding it hard to climb the stairs at work and actually stopped a little while ago, or running around the house with the kids, I'm tired so damn fast.
We got this and we'll all be fitter and healthier in the end!
