If you think you might be an artist, make art. You may suffer a great deal because you are not making anything and you are supposed to make something. If you are hesitating because of practical concerns, e.g. you think your art isn’t good and won’t sell or “get you anywhere,” then you’re missing the point and maybe you forgot that art can free us from such quotidian concerns. Making art is an essential practice for humans and belongs on your practical “to do” list regardless of whether the art itself is practical.
