> you look better each day than the day before

Again, this is only true if you are unfit. I have been doing sports regularly for the last decade and my body is in good shape. My doc says I'm healthy. Loosing more weight would make me underweight...

Yes, I could become more fit, but training for endurance won't change my body visibly.

> And everyday, as you think back to when you could only do X amount of Y

I have come back super-fit from two-week vacations were I spend nearly everyday mountainbiking or hiking. Back in the city, I can't spend 10-12 hours outdoors everyday. At the very best, I'm maintaining that fitness level, but most likely it is getting worse.

When I was younger, I had the attitude you're prescribing: My fitness became worse, and it was emotionally affecting me because I was searching for a feeling of success. Now I'm aware that my fitness level changes seasonally, reaching bottom at the end of the winter and peaking in the summer. I'm fine with it and I enjoy doing sports just for the sake of it.
