Ride the bus home with nothing in your ears. Strange how much your head has been trying to tell you.

Headphones let you decide what you think about, which is useful right up to the point where it becomes the only setting. Take them out and the backlog arrives: the thing you meant to say, the worry you parked, the idea that needed ten quiet minutes. None of it is new information, it has simply been waiting for a gap.

Try one ride this week with nothing playing. It will be uncomfortable for about four minutes and then it will not be. Write down the one that still seems worth it when you get off.
