The idea that art-making is a luxury seems to me beside the point of being an artist. An artist doesn’t dabble or have their practice as a hobby. The artist makes art because it is what they do, whether anyone is looking or listening or not, and whether it comes at a great cost or not. It is not a matter of temperament but rather a matter of nature. Good artists might be made good through study or rehearsal but artists without qualification, good or bad, are born that way.
