Meredith, I think the best way is a little of both.

Accepting your limitations, but keeping posted on the latest medical developments. Everyday new medications come out. I would keep my hope up, and stay informed. I would concentrate on targeted therapy. Isn't swimming a good sport for arthritis? Maybe you can try to do sports that way.

It must be very hard, especially if you love to move. Believe me, I'll let you know if I ever hear of any new discoveries to combat arthritis.
