Well done. You have expressed ideas quite clearly that I have been trying to express with very ‘neurosciency’ kinds of words. I have developed a brain/body compatible theory of personality that tries to explain the science of what you just said. Basically I believe we are each making sense of information in the world in the ways that make the most sense to us based upon our sensory, motor, and nervous systems, all of which are constantly changing over time.
The stagnant psychologically generated terms we now use to classify and categorize people are misleading and confusing because each one of us humans responds to new information with a whole new set of memories and experiences from one day to the next.
