Personality is repeated patterns of behavior that can be observed and measured.
(I suspect our unconscious stradgies, tendencies and tastes, that we use to make marks and create compositions reflect our personality. Our conscious strategies that are used to manage our personality is our ego. My personal view is that for each of us, our tendencies are an authentic elements of our personalities, while the stradgies and tastes that we develope are overlays set onto us by the cultures that we are embedded in.)
As a practicing artist, what you choose to make and how you choose to make it develops an observable pattern structure. It reflects a world view shared with our ego, even if what is being reflected is challenge to the status quo.
