Thought is subject to choice.
Emotion follows thought.
Thought and behaviour are subject to choice / freewill.
It is via thought that emotion is controlled.
Thought initiates emotion, but the type of emotion initiated is dictated by the values relevant to the thought.
Values are subject to judgement.
Values can be reassessed and rearranged according to better judgement.
We can subject anything to our judgement.
Choice is preceded by judgement.
