Weekends often become extensions of the workweek. You catch up on tasks, run errands, and fill the time with obligations. Leave Saturday completely unscheduled. No plans. No to-do lists. Just open time.
This day becomes a buffer. It gives you space to rest, to follow curiosity, to do nothing. It prevents the weekend from becoming just more work time. It ensures you have at least one day that feels different from the week.
You might use Saturday for rest, for hobbies, for spontaneous activities, or for nothing at all. The point is not what you do. The point is that the day is open and unplanned, giving you freedom to respond to the moment.
Try it this Saturday. Leave the day completely unscheduled. See what emerges when you have open time. Notice how different the day feels when it is not filled with obligations.
