Three things to try
The book asks to be tried rather than believed. Here are three of its arguments with the words taken away. None of them has a score or anything to win, and each one explains itself after you have tried it.
Four people, one trolley
Everyone pushes exactly as hard, whichever way they face. Get the trolley 15 metres.
Everyone pushing as hard as they can. It does not move one centimetre.
Drag a person to move them around the trolley, or tab to one and use the arrow keys. Nobody pushes any harder either way.
What just happenedOpens when the trolley arrives.
A day, drifting past
Things arrive all day, and most of them are not addressed to you. Tap something to hold it. Hold as many as you like, and watch what finishes.
Nothing held. Everything drifts past, and nothing is lost by letting it.
What just happenedOpens in the evening.
Three seconds
Three moments arrive, each with something you could say straight away. Nothing is timed against you and nothing can be failed.
Three moments arrive. Each one offers you something to say straight away.
There is no timer and nothing to lose. Take as long as you like — that is the whole of it.
What just happenedOpens after the third moment.
