Why the fill seems right

Before I argue with the fill, I want to be fair to it, because most of it is good and the people who fill every minute are usually the curious ones.

It's pleasant. A good podcast is good company. The radio in the kitchen makes cooking better. Music in the shower is one of the small joys of a morning.

It's learning. You know more about the Byzantine Empire than you did a year ago. You've heard interviews you'd never have read. The fill is an education you didn't have time for, fitted into minutes you weren't using.

It's company. A voice in your ear on a walk is a walk with someone. The house with the radio on is a house with people in it.

It's efficient. The walk to the car is four wasted minutes unless something's in them. The queue is dead time. The fill turns dead time into something.

Silence is awkward, alone as well as in company. A quiet room has a quality to it that you'd rather not sit in.

The mind goes to bad places. Left alone, it finds the thing you said in the meeting, the email you haven't answered, the worry about your mother. The fill keeps it somewhere better.

Everyone does it. Look down any street. The fill is what a modern head has in it.

It's habit. The headphones go in at the door because they've gone in at the door for years, and the hand that reaches for the radio in the kitchen is a hand that's reached for it since you moved in. Nobody decides the fill each morning. It's the shape the morning has.

And it's free, or nearly. There's more good audio available than you could hear in a lifetime, and it costs nothing to have it on.

There are needs under all of this. For pleasure in ordinary minutes. For learning. For company. For the mind not to go where it goes. Those are real, and the method later in the book keeps most of the fill for exactly those reasons. What I'll show is that the fill, as a default rather than a choice, meets the needs while quietly costing something that only quiet provides, and that the discomfort it's protecting you from is smaller and shorter than it feels, and has a job to do.
