For art, it’s not skill or technique that makes someone an artist. It is simply the terrifying decision that what you make is art. Terrifying because the only gatekeeper to being an artist is you. Declare yourself an artist and you are. Call what you made art and it is.
Yup. When I was painting, I spent some time thinking about what it "meant" to be an artist. I finally decided that an artist is just executing a vision in some particular medium.
