Use.

This year my walking has become a lot better. It has taken time, but I can now walk further than I ever thought I would be able to. It doesn't mean that my walking is perfect, I still live with a constant sense of adjustment, and the knowledge that I am one missed dropped foot from a fall. My time walking has to be watched as my energy, when its up, is totally gone. And, its alright.
 I'm healthier than I have been in years, within the parameters I've been given. Best use that then.
