I am going to assume that I don’t understand your question because of the nature of how I work, rather than assume there is anything wrong with the question. I don’t get it.
I wake up neutral, The mood is not good or bad, I am just conscious of my existence. Then things happen, and that is what determines my mood. However it does not determine it for the entire day, just for however long is warranted for the situation.
Regarding choices, I seem to have the ability to turn off my caring mechanism. No matter how serious or bad or good a situation is, I can always choose at the drop of a hat that I just don’t care anymore, and I turn off all emotion. However, if I choose to feel, I feel whatever is imposed on me to feel. I have no control over emotions.
