Step 1: Forget about the laundry, what's for dinner, taking your car in, making dentist appointments for the kids, getting a baby shower planned, cleaning the bathroom, completing your Relief Society Report, finishing your latest craft and all other things on your TO DO list.
Step 2: Go to the park
Step 3: Play with your kids - even if it means racing cars down the slide for an entire hour.
additional note: If you do not have kids you may borrow mine in order to do this simple exercise.
