I've been called a jack of all trades. Perhaps. I've known several.
Due to elicitation/HUMINT I'm refraining from specific people and their abilities. But nonetheless, we are blessed in these united States with many 'jacks/jills'.
I have had many jobs, met many people. I can identify with many ways of life. Rich poor blue/white collar and an ability to talk with almost anyone.
It is an inability with most liberals/progressives/collectivists. Ivory towers are disguised with mud-slinging.
Psychopaths/sociopaths are unable to relate. They only stir discord and hope people are stupid/naïve enough to swallow the poison.
Myself and my Dad, my father in-law etal have/had that ability to relate to many. it is passed onto the kids.
Such skills are not only an experience of jobs. The jobs experience you.
Master of one -s-.
