Biologically, human psychology in a vast network of interconnected cells bathed in blood and chemistry.
Intellectually, we typically reduce this enormously complex system into terms that reflect types of behavior, such as narcissism, anxiety, dark triad, bipolar, OCD, self-esteme, etc.
While these reductions are helpful for understanding human psychology and showing us where to focus our attention, they cannot be expected to optimize our psychology.
To date, the human brain is the most complex thing we know of in the universe.
Once you have seen through your mom’s narcissism and its effects on you and have consequently been able to overcome much of your anxiety, are you then psychologically optimized?
Of course not. At best, you are then able to function better and feel better and, with luck, forgive your mom whose persistence in her narcissism was due to her enormously complex brain, same as yours.
So how do you optimize? Or how could your mom have optimized before you were born?
Clearly, it would have taken her years to correct her narcissism, let alone optimize her psychology. Same goes for you.
This is why all people need a system that works every day for many years. There is no other way to do it because optimizing a complex system requires tinkering at all levels over a long period of time and cannot be done quickly or be based simply on top-down category assessments.
The FIML systems works every day for many years gradually optimizing one part after another of our complex psychological systems. With current technology and understanding, I do not believe there is a quicker or more thorough way to do that.
An impediment to doing FIML is few people realize that their psychology is far from optimized. A sad aspect of doing FIML is realizing that you live in a world like that.
