The last point is particularly useful, and quite reminiscent of what 'The Now Habit'[1][2] advocates. Some weeks I get so completely burned out, I have to force myself to do nothing but 'veg out' by watching endless netflix shows through the weekend without thinking about anything else. It's hard to allow it at first because it feels like a ludicrous waste of time, but it becomes surprisingly refreshing by the end of it.
