Your HI Mind
Humanity in Action.
The Nature of Being Human.
But, Why Suggest a New Model?
The HI Mind approach is, I suggest, important for a number of reasons, such as these:

To provide a better understanding of how some of the major psychological approaches (Behavioural, Social-Learning, Cognitive, Mindfulness, and experiential/theological) interact together.

To better understand the significance of, and relief from, chronic problems such as self-destructive habits, emotion-based depression, anxiety, mood disorders, languishing, and burn-out.

To more easily understand mental biases and potential internal conflicts.

To evolve new ways to encourage mental wellbeing.

To better understand the role of intellect and it's relationship to personality.

To give an improved understanding of our motivations, which are often internally competitive, and to evolve better strategies to promote clear and rewarding personal and societal purposes.

To begin to understand why political and broader financial and cultural systems seem to so readily end up producing conflict and general social failure.

To achieve greater understanding of questions such as 'How does brainwashing work?', 'What happens when we don't care any more?', 'Why do we procrastinate so much?', 'What is depression for?', and so on.
I find the HI Mind useful to imagine how some internal processes play out, but it can be important to remember this model is not reality. There is no single place in our brains where each of these 'Focuses' exist. These 'Focuses' are not actual independent and separate minds. They are, perhaps, functional aspects of our one mind. Using a model such as this, which focusses on function, can make it easier to understand some of the processing that goes on in our one mind and some of the problems that can appear when we have multiple purposes or when our mind is out of 'balance'. Any model of the mind is, of course, a gross simplification of the interconnectedness of our mental processes based in our brain, nervous system, and body.
