Relaxing and not doing anything is important to me. Days when nothing should happen and time may just pass. The biggest part for me is about disconnecting the brain, which normally spins with ideas, which are about to be written down.
From the writing school I went to in 1993-94, the notebook would never leave my hand. Constantly searching for the perfect observation that amazed my readers.
But at least once a week, my brain is free. Turn it off completely and then it is full of energy again…
