Lately, I've done the opposite, adding a longer walk in the afternoon and sometimes (today, for instance) in the morning, too; strolling to a Metro stop farther from my office, savoring the time I spend in the places in between.
En route I think of my great commutes in New York City, walking to and from midtown Manhattan from the Upper West Side and, later on, the Village.
The goal is to exercise, decompress, let the day begin (or end) on a vigorous, active, mind-toggling note. The reality is even better.
