Follow-through
Why proof-based focus can improve follow-through
“Focus for 20 minutes” describes time spent. “Finish these ten questions” describes a result. That difference matters.
A timer does not define done
A timed session can help you begin, but the timer may finish before the task does. Defining proof first gives the session an observable ending instead of relying only on elapsed time.
The finish line becomes concrete
Before the lock starts, describe what the finished task should look like. A completed form, submitted assignment, clean surface, exported document, or checked-off list is easier to act on than a broad intention.
Proof adds a final action
Uploading evidence makes completion explicit. You return to the app, show the result, and close the loop instead of deciding halfway through that the work is probably good enough.
Useful proof depends on the task
A photo may suit homework, cleaning, cooking, or a physical project. A document or screenshot may suit writing and admin work. Use the smallest amount of evidence that clearly shows the result.
Completion is not perfection
Done checks whether the evidence matches the finish line you entered. It is not grading the quality of the work unless you specifically made correctness part of the task.
