Afternoons can fray. The edges of the day loosen, and attention begins to wander. A light method helps. Write short notes before lunch that carry you through the later hours. Not plans. Not declarations. Just a few lines that tell you where to place your hands next.
Structure them simply. A verb. A noun. A brief result. Send invoice. Edit paragraph three. Sweep the shelf. When you return after a break, you are already in motion. There is no need to search for a starting place because you left one in the open.
This is not about productivity. It is about respect for the hours that remain. You do not force progress. You make it easier for progress to appear. If the day changes, change with it. Cross out a line and write a better one. The page will absorb the update and offer it back without complaint.
You end with a clean surface and a clear step tomorrow. That is a good afternoon.
