You will never figure yourself out by answering questionnaires or trying to match yourself with a psychological metric or type.
Beyond that, you will absolutely never optimize your psychology and life using those methods.
The right way to grasp and optimize your psychology is to understand how it functions in real-time real-life situations.
To do this you have to take control of your own life and use a technique like FIML that allows you to observe yourself in real-time real-life situations.
I honestly do not think there is any other way.
