Are you a Hobbyist or a Professional... or are you something else. Defining our art by money is a problematic approach to our work because it turns our art into a product or a widget. A professional is a working artist. Either an employee or freelancer, someone who gets paid.
What are you if money doesn't define your art? The terms working artist, hobbyist, aspiring artist, creative, etc are all problematic for various reasons. So, if you create for reasons other than employment, money or fun, how do you self-identify?
