The Difference Between Motion and Causation

Picture two people at the end of the same working day.

The first answered ninety messages, sat in six meetings, put out three fires, and is exhausted. Ask what she decided today and she has to think. The second answered twenty messages, sat in two meetings, and spent three hours on the one thing that will matter in a year. He is also tired, but it is a different tiredness, the kind that comes with something to show for it.

Both were in motion all day. Only one of them caused anything.

A ball on a pool table

Physics has a clean picture for this. On a pool table, every ball is in motion after the break. Balls bounce off cushions, collide, roll into pockets. All of them are moving. But only one thing on the table caused the motion: the cue. Everything else is effect.

Most of us live as balls. We move a great deal. We are struck by a message and roll into a reply. We are struck by someone's urgency and roll into their emergency. By evening we have travelled a long way, and none of it was our direction.

The book calls the alternative the Prime Mover: the one who is the cause of their day rather than its effect. Not a person who never gets struck, but one who sets a direction first, and meets the collisions from there.

The number that tells you which one you are

There is one measure in the book that I think is the most honest in it, and it is embarrassingly simple. At the end of the day, ask: what share of my energy went to things I chose, and what share went to things that chose me?

The book calls this the chosen-versus-reactive ratio. The target is about four fifths chosen. Most people, measuring honestly for the first time, find they are nearer one fifth. The rest of the day was reaction: motion, not cause.

The point of measuring is not guilt. It is that you cannot steer what you do not see, and a single number, scored at the evening shutdown, makes the pattern visible within a week.

Why reaction feels like work

Reaction is not lazy. That is what makes it such a good disguise. Answering the ninety messages is effortful. It feels productive. It even earns thanks. But effort spent as an effect of other people's causes does not accumulate into anything. Tomorrow there are ninety more.

Causation, by contrast, compounds. The three hours on the thing that matters in a year are still there next month. They become the foundation the next three hours stand on. This is why the second person in the story is not just less exhausted but, over time, further ahead by a margin that looks unfair.

The smallest possible move

Tomorrow morning, before any screen, write one line: the single thing that, if it moved today, would make the day a success. That line is the cue. Everything else on the table is a ball.

Then, whenever something arrives, ask a single question before you touch it: is this on the line, or is it striking me? If it is on the line, act. If it is striking you, let it wait in a queue. A queue is not a scatter. A queue moves, but in your order.

At the end of the day, look at the line. Did it move? That is the only score. Ninety messages answered is motion. One line moved is cause.
