En route to normalcy And habit formation

Finally a fortnight is over and the cast on my foot has been removed. The doctor was happy with the progress. Voila now I am back to normal life. Ah how wonderful it sounds. Normal. Yet when I stepped on my foot ( that was in the cast) I had actually forgotten to walk. And it was just 14 days. Pins and needles shot through my leg. Suddenly new muscles groaned and hey I was limping.
So all it takes is 14 days to create a change!  So another fortnight and I ought to be running. Would this be the same with habits?
This is inspiring is it not.
