Mowing the lawn is my favorite. Seriously. And exactly for the reasons you mentioned. Alone with a noise loud enough to drown out my singing and my out-loud reactions to the narrator of the audible book I’m listening to. I have one task…to drive that tractor in a straight line. It puts me in a good mood every single time and for some reason I’m guarenteed to come away with new ideas, solutions to problems, and a beautiful lawn!
