Work/rest cycle

[Ghost of the dead horse]

How does it affect you? How would you describe it?

Here's my attempt.
Work:
-demands concentration
-takes effort
-excites me to the point of exhaustion, or..
-tires to the point of exhaustion

rest:
-demands so little concentration that concentration is not a main part of it
-goes naturally
-excites me in the way i want
-tires me in the way i want

What's your analysis?

 

[Ghost of the dead horse]

What I meant was asking you to give a simple psychological model of this cycle.. not unlike filling in the details to this diagram or something

(with the something something describing whatever goes around in person's head, knowing or unknowing.. )
