I find waiting for things physically exhausting. Waiting in lines, waiting sitting in a room, waiting on friends to decide what they want to eat, walking really slowly with an elderly relative: I find it all physically exhausting even though very little physical energy is required.
I’d had intermittent success with that. The bigger problem is I can’t properly develop habits. So I’ll be good about avoid distractions for a week or two then my focus shifts to some other interest and I’ve forgotten to avoid the dopamine box
