Last time, I wrote about how it takes 21 days to form a new habit. Today I put that to the test. I forgot to put on the pedometer in my rush to get out the door this morning. But, based on the weeks of using the pedometer, I felt propelled to walk across town rather than take the subway, even if I couldn't watch the miles ticking up. So the pedometer did its job in getting me to make better choices, even without hanging from my waistband.
