There are only so many daily routines one can work into a twenty-four hour period, and the addition of a new routine — or the re-initiation, rather, of an old routine — leaves less time, logically, for other routines. So when I tried finally to start working an exercise routine into my day, I found that, after school, jazz dance shuttle service, dinner, time with the kids, goodnight routines, and a short workout that I was left with ten minutes until my bedtime. So something’s got to go.
