How to use the online timer
Twenty-five minutes of genuine single-tasking is more demanding than it sounds, and rarer than most people think. The block is not really about the length; it is about doing one thing for the whole of it, without the small switches to email, messages and browser tabs that feel free and are not. Each switch costs several minutes of getting back to where you were, and a heavily interrupted hour can contain less real work than an uninterrupted twenty-five minutes.
The block is decided before it starts. Notifications off, phone in another room rather than face down, one document open and one specific outcome in mind. Willpower halfway through is a poor substitute for removing the temptation beforehand, and the minute of setting up is the highest-value minute in the whole block.
Attention will drift regardless, and that is not a failure of the method. The skill is noticing the drift and returning to the task rather than following it to its conclusion and abandoning the block. When the twenty-five minutes end, stop properly and leave the screen for a few minutes; a break spent on a different screen leaves you no fresher, and the next block will show it.
Common questions
Is twenty-five minutes not too short for real work?
It is short by design, which makes starting easy. If the work keeps overrunning and stopping feels wrong, that is a sign the task suits a longer block rather than a fault in the method.
My attention drifts halfway through. Am I doing it wrong?
No, drifting is normal. The skill is noticing it and returning to the task rather than following the thought and abandoning the block altogether.
