Any chance of changing the scenery? Working somewhere different could reboot you.
Try a café, library, garden, spare room or anywhere that doesn't scream “same old,
same old.” Productivity doesn't mean working continuously for eight hours, either.
Take breaks. Walk. Stretch. Look at something other than a screen. Your brain
could be bored senseless, begging for stimulation.
See how the movement of the Sun, Moon, Mercury, Venus, and Mars influence your every day.
How you advance and progress.
