Listen to your body, when? All the time. Listen to your brain, when? Hmm, jury is still out on that one. We have to depend upon ourselves for so much, I for one would plan out events so I could pace myself physically (and honestly decide if the effort was worth the event).
But I have found that even now that I feel 100% more mobile then I did a year ago, I still listen to that inner voice that tells me I can't do something.
A year ago, walking to my mailbox (I know I've said this many times, so please forgive yet another reference) was a chore. I would pull into the driveway, park the car at the end, then get the mail and drive the rest of the way up to the house. I can now walk to that mailbox and back and the only reason I park at the end (when i do) is because currently my driveway is a sheet of ice and the fear of a fall outweighs the need to feel like I can walk it now.
Earlier this week, I walked to the post office from my office. It is a little over a block away (a little further than my mailbox), and it was the first time I had done it in the year and half that I have worked there. Typically I go to the post office on my way into work, drive there, then drive on to the parking lot. I walk further to and from my car every day, but something in my head said I can't walk to the post office, so I never did, until this week.
I was almost in tears when I came out of the post office and turned to head back, I could actually see the pillars on the front of our building from where I stood in front of the post office - it was that close. I know that walk would have been very painful when I first started my job and the fear of that pain has kept me from even considering it, until now - which by the way was a fluke that I even did so, I had parked on the street and while I was walking back to my car I noticed how close the post office was and decided I would walk to it, instead of driving to it as I left for the day.
This is a long post about a short walk; but it is monumental for me emotionally, I still have a lot to work on in thinking I can do something and not just continuing to immediately say "I can't do that".
