My dogs can tell the difference between the sound of emptying a clean dishwasher and filling a dirty one. They can even tell the difference between the sound of doing dishes and of moving food from one container into another (when food inevitably falls on the floor).
Sure, it’s Pavlovian, but it also speaks to how much you can know by honing in on the one thing that matters most to the outcome that you care about.
Do you know what that one thing is for you? If not, how can you find out?
