Background
About focus
Focus is the ability to keep your attention on one chosen thing while the rest of the world negotiates for it. It is trainable — not through willpower alone, but through structure: shorter committed blocks, a clear intention for each block, fewer open loops, and recovery before fatigue collapses the session.
Two ideas do most of the heavy lifting. First, make the start easy: a 25-minute timer and a one-sentence intention remove the ambiguity that causes procrastination. Second, protect the middle: silence what can be silenced and write down (rather than chase) whatever pops into your head.
This is the site’s core topic. The articles below cover focus routines, the Pomodoro technique, attention science, and honest self-testing — everything designed to be applied in minutes, not someday.

FAQ
Common questions about focus
How do I improve my focus?
Start with structure, not willpower: pick one task, set a 25-minute timer, put the phone out of reach, and write down stray thoughts instead of chasing them. Then protect sleep and take real breaks — focus follows recovery.
Why can’t I focus even when I want to?
Common causes: sleep debt, too many open loops, a task that is vague ("work on report" vs "draft the intro"), and an environment full of cues to switch. Fixing the task definition and the environment usually beats trying harder.
