Rest, relaxation are like sleep. If you're not waking up refreshed and in a good mood, it may be because you were unable to 'turn off the engine'.

Creativity doesn't come from thinking. Nor does enjoying what others have created (and letting them know). Nor does having a sense of humor (try not having one for a while ... see what that does for your social life). And trying to do 10 things at once leads to mistakes and doing far less of them to the best of your ability. Let the machines enjoy being a machine.

No worries.
