READY
Forty minutes is a school period in much of the world, and that is not an accident of timetabling. It is roughly the point at which a room full of people stops absorbing a single subject, which is why the length survived long after anyone remembered choosing it.
It is also a quick wash cycle, a sensible block for one piece of work, and the length of a walk that gets you somewhere. Long enough to finish something, short enough to fit two of them into a morning with a break between.
The tip: decide what finished looks like before you start, and put it somewhere you can see. A forty minute block with a subject drifts; a forty minute block with a finish line does not. If the job is bigger than forty minutes, write down what these forty are meant to produce rather than what the whole thing needs.
Press start or the space bar. Add a minute if you are nearly there, or press R to come back to forty.
It depends on the work. Anything with a long warm-up, like writing or code, tends to suit longer blocks; anything you keep avoiding suits shorter ones, because starting is the expensive part.
Five to ten minutes, away from a screen. The break exists to let attention recover, and checking messages is the one activity guaranteed not to do that.
Tap the minutes on the readout and type. Reset brings back the forty this page is for, so experimenting costs you nothing.
