The basic first idea is this: learn to walk.
Obviously, I know how to walk. In general. I can get from point A to point B.
The trick is that I never particularly do any walking for the sake of walking. And I certainly don't go any significant distances.
So the first goal has been to walk a mile every day.
I live in an area full of walking trails and really scenic routes, so finding a place to walk isn't a problem. There are almost too many routes to choose from.
The problem is that where I live isn't particularly flat, and part of the goal of walking a mile every day is to build up endurance and muscle around a bad knee. My knee isn't terrible, but it gives me just enough trouble that I need to do something about it.
I'm not really succeeding at this step yet, and I'm convinced that it's the hardest one. Because what this step is really about, among all the things I've mentioned, is making myself make time for this. It's about not getting distracted, not changing my mind, not making excuses. And so far that's a lot of what I'm doing. I didn't take my walk today because I've been cleaning my house because my sister is here visiting, and we had to gather paperwork for a meeting.
So that's the basic goal right now: walk one mile, every day, despite the weather. Just get used to walking no matter what.
