Rosemary for Remembrance

Something that may help: work with your PT to set reasonable, achievable goals, then give yourself permission to quit when you reach the halfway point if you really need to. But be honest with yourself at that halfway point: can you go another minute or not? If you can, do so, then check again. If you can't, stop. I did this many years ago as a way of getting into shape (for probably the first time in my life) and it not only did the trick but, more importantly, taught me to let my body be honest with me. What turned out to be important wasn't the times I kept going but the times I let myself turn around - and those, in turn, got to be fewer and fewer, as I really did develop the ability to go another block.
