There’s a lot to unpack here Terry.
If you impulse buy affordable art by the dump truck load to fill an emptiness inside.,,.,then....scream when a grail comes by....its time to change tactics.
There are many things “out of reach” either because of price or availability. However “focus” as a strategy can pay off. That means let the chafe sail by, keep your finger off the bid or buy now button. Save your cash. Then go hard for that one piece you’ve wanted all your collecting life.
Don’t worry about what might never appear for sale. Most things you’re looking for reveal themselves. They might not be for sale but it puts your mind at ease.
