What if only artists who could sell their works painted? What if only professional dancers danced? What if no one would sing unless you payed them?
If, as an artist, you assumed your work was worthless because no one bought it, how would anyone ever even begin to create? How about all the wonderful artists who have never sold anything?
Some things have innate worth. Worth from the action of doing them, worth because of their innate meaning.
