There is a rhythm to making things. It does not always match the rhythm of a calendar.
Step outside the frame
When a piece of work stops moving, the answer is not always more effort. Change the setting. Walk somewhere without headphones. Read something outside your usual interests. Distance lets you see the shape of a problem instead of only its edges.
Allow an interval
Space between sessions is part of the work. An idea that felt tangled in the evening may be simple the next morning. Leave yourself a short note about where you stopped, then close the notebook. Rest is useful even when it produces nothing you can measure.
Return with intention
Slowing down is not the same as standing still. Choose one small thing to resolve when you return. A clearer opening, a simpler layout, one image that finally feels right. Progress often looks quiet from the outside.
