I love feeling fit--I've gone from barely being able to run 60 seconds to being able to run 7+ miles.
Going clothes shopping is no longer depressing.
A vendor in our office yesterday commented, "Look how skinny you are." Appropriate? No, not really (though it was in a context that made it less creepy than it might sound). But kinda cool anyway? Yep. And even before I was really overweight, nobody would ever have said that to me.
So much is just *easier* now that I'm not carrying around the equivalent of my 9-year-old all the time!
