I had to get over the idea of the runner's high or the idea that I was going to have this euphoric experience when exercising. I know it happens for some people, but it hasn't happened for me, and I don't think it's going to. I had to stop being disappointed about that.

I also had to get over the idea that I was going to be able to do a lot of running on the ground. I run on the elliptical, but that's so different from running on the ground. Running on the ground really activates my interstitial cystitis, and it hurts my knees. I do it occasionally because it does work different muscles (or when I'm on vacation and have no other exercise options), but I had originally thought I would turn into this person who could run around the neighborhood, and I just can't.

Congratulations on figuring otu what works for you. That's awesome.
