How is creativity valued? Is there a way to determine a price ? Not really. There is no intrinsic value that can serve as a baseline. As in the context of an art auction from which point bidders begin to compete, value is established based on supply versus demand, and the process is fairly subjective.
Therefore, the ‘intermediate ‘value’ is established when 2 or more people bid on something that they believe has personal significance. If that’s true, art has no absolute cost. It is the personal meaning that determines the value.
When creating, never ask; ‘how can I make this worth more?’ Your motive should start and end with, how does this create meaning in my life and the lives of others? Achieve that and you and your art are forever invaluable.
