Step 1. Gather Everything in One Place
Write down everything occupying your attention: work tasks, commitments, shopping lists, calls, and chores. Do not categorize or schedule them yet. The goal of step one is to clear working memory.
Remove obvious duplicates and tasks you no longer need. If an entry cannot be executed directly, rephrase it as a concrete physical action: replace "work on report" with "gather numbers for report".
Step 2. Select the Primary Result of the Day
Highlight one task whose completion makes the day feel productive. Then add one or two supporting tasks. Remaining tasks do not vanish, but they stop competing for top priority.
Check fixed commitments: meetings, deadlines, and dependencies on others. Urgent items are not always important, but real deadlines cannot be ignored.
Step 3. Allocate Time for Tasks
Place fixed events into your calendar first, followed by your primary task, and then smaller items. Estimate using normal rather than ideal speed: if a task usually takes 90 minutes, do not allocate 40 minutes.
Keep at least 20% of your time free as a buffer. This reserve is not for new tasks, but for delays, context switches, and unexpected requests.
Step 4. End the Day with a Short Review
Check off completed items, and do not automatically roll over unfinished tasks to tomorrow. First decide whether they remain important and when you actually have capacity.
Log one reason why your plan changed. Over a few days, repeating patterns will emerge: overly optimistic estimates, extra meetings, or starting with trivial tasks.
