Pick one task
A focus block works best when it has one clear task. Avoid starting with a vague goal like work on everything.
Set a small time window
Choose a window that feels easy to begin. Twenty-five or thirty minutes is often enough to make progress.
Remove one distraction
You do not need a perfect environment. Just remove the most obvious distraction before starting.
End with a next step
Before stopping, write the next action. This makes it easier to continue later without rebuilding momentum.
