Today I pushed myself farther than I had in a long time by going on a mile and half hike/walk. I made it but barely, my ankles and thighs hurt but I made it. I'm stiff and sore hours later but I did it. I'm proud of myself even if I'm in pain. 
Next time it will be easier, each time will be better. 
I'm working at it, I'm making progress, I'm moving forward.
