Run everywhere you go. If you must cross a street, run across the street. If you must cross a field, run across the field. If you must cross the kitchen to the sink, run across the kitchen to the sink. When someone rings a dinner bell, run to get your dinner. When someone points up toward the sky, run to see if it’s an airplane, planet, or cloud. Run up the stairs, run down the stairs. Run through doorways and around blind corners. Run to put your shoes on, then run in your shoes. Run for a quarter mile, run for a mile. Run for eighteen inches if that’s all there is to run.
