How to focus better, without relying on willpower
Shorten the block until starting is easier than avoiding. Almost everyone who fails at 25 minutes succeeds at 15, and the difference is not discipline.
Distraction is usually a symptom rather than a cause. When a work block is longer than your current capacity, your attention leaves before the block does. Making the block shorter than your capacity fixes the same problem that hours of self criticism will not.
Four things that work
1. Make the unit smaller than feels impressive
The correct block length is the one you will actually finish today, not the one that sounds serious. Fifteen minutes finished is worth more than forty five abandoned.
2. Put the timer where you can see it
A countdown hidden behind other windows stops working, because checking it costs a context switch and the switch is what you were avoiding. A timer that is always visible removes the decision entirely.
3. Write the interruption down
Most intrusive thoughts during focused work are not urgent, they are just unfinished. Writing them on paper closes the loop cheaply. Acting on them costs you the block.
4. Take the break properly
A break spent on a feed is not recovery, it is a different kind of attention spend. Get up, look at something further than an arm away, drink water. Five minutes of that restores more than fifteen minutes of scrolling.

Measure finished time, not intentions
If you want concentration to improve, watch one number: minutes of finished focus per day. It rises slowly and it does not lie. A streak of days where you hit a modest goal will change your behaviour more than any productivity system, because it turns focus into something with visible evidence.
